How We Ranked the Best Watches Released in September 2026
This ranking asks a simple question: what makes a September 2026 watch worth serious attention? The answer is not limited to price, rarity, or the number of complications. We weigh five areas: horological interest, originality, collector appeal, everyday practicality, and the strength of the published information. The result is an editorial selection, not an affiliate buying list.
Technical achievement matters, but it needs context. The A. Lange & Söhne TRIPLE SPLIT is described as a split-seconds chronograph that can measure intermediate, comparative, and overall times for up to twelve hours. Its L132.1 manufacture caliber contains 567 components. The edition is limited to 100 pieces in 950 platinum. These details give it clear interest for collectors focused on complex mechanical watches. They also point to a specialized proposition rather than an obvious choice for every buyer.
Size is part of that assessment. The TRIPLE SPLIT measures 43.2mm across and 15.6mm thick. Those dimensions may affect its suitability for regular wear, depending on the wearer and intended use. The watch also displays the remaining power reserve, offers a quoted 55-hour reserve, and uses a sapphire-crystal caseback. Such details help explain both its mechanical appeal and the way its design serves that purpose.
Practicality receives equal consideration. We look at the published information on legibility, versatility, case proportions, design coherence, movement interest, and intended use. A technically ambitious watch may rank well because of what its movement achieves. A simpler release may make a stronger case for regular wear because its design, dimensions, and functions work together more effectively. The ranking treats these as different strengths, rather than assuming that complication automatically makes a watch better.
Originality also requires more than an unusual function. We ask whether the technical choices support the watch’s purpose, whether the case and display express a clear idea, and whether the release offers a distinctive answer within its category. A familiar complication can still matter when its execution or presentation is purposeful. Complexity alone is not enough if it does not add a clear identity or useful function.
Published evidence sets a further limit. Details about mechanics, dimensions, production, prices, and design must be supported by available material. If a specification is not published, or if accounts differ, the uncertainty remains visible. The new TRIPLE SPLIT, for example, was scheduled for presentation during the Concours of Elegance at Hampton Court Palace during the first weekend of September. That date helps establish the release’s place in the month, but it does not settle every question about the watch. This list therefore explains why the selected releases deserve attention; it does not declare one universally superior or direct every reader toward a purchase.
How the Five September 2026 Releases Compare
How the Five September 2026 Releases Compare
There is no single specification that fairly ranks these five releases. They cover specialized mechanical timing, calendar displays, a hybrid digital format, and a more conventional automatic chronograph. The table separates the published information so that case dimensions, movement details, functions, power reserve, water resistance, edition size, and price are not treated as interchangeable measures.
| Model | Case size or dimensions | Movement or caliber | Published functions |
|---|---|---|---|
| A. Lange & Söhne TRIPLE SPLIT | 43.2mm diameter; 15.6mm height | L132.1 manufacture caliber | Split-seconds chronograph capable of measuring intermediate, comparative, and overall times for up to 12 hours |
| Rolex Perpetual Padellone | 39mm | 5Hz caliber 7190 | Instantaneous annual calendar with the patented Haplos system; moon phase |
| Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Azure Dial | Not reported | Cal. 1120 QP/1 automatic; 4.05mm movement thickness | Perpetual calendar |
| H. Moser & Cie. Off-Grid | 42.6mm steel case | Not reported | Hybrid digital display; GMT, split-seconds chronograph, perpetual calendar, moon phase, sunrise and sunset times, alarm, and travel translation mode; no smartphone connection |
| Girard-Perregaux Laureato Chronograph Williams Edition 42mm | 42mm | GP03300 automatic; 45 jewels | Chronograph |
The A. Lange & Söhne TRIPLE SPLIT is the most narrowly specialized watch in this group. Its split-seconds chronograph is specified to measure intermediate, comparative, and overall times for up to 12 hours. The L132.1 manufacture caliber provides a 55-hour power reserve, with an indication of the remaining reserve. Its 43.2mm by 15.6mm platinum case and 100-piece limitation place the emphasis on the complication and its rarity rather than on compact dimensions.
The calendar watches present a different comparison. Rolex’s Perpetual Padellone combines a 39mm case with the 5Hz caliber 7190, an instantaneous annual calendar using the patented Haplos system, and a moon-phase display. The model is inspired by the late-1940s reference 8171. Vacheron Constantin’s Overseas Perpetual Calendar Ultra-Thin instead centers on the automatic Cal. 1120 QP/1, whose movement measures 4.05mm thick; the watch has 50m water resistance and is supplied with one white-gold bracelet and two rubber bracelets. Its listed price is $132,000.
The H. Moser & Cie. Off-Grid is not directly comparable with the mechanical watches on movement architecture alone. Its 42.6mm steel case houses a hybrid digital display with an unusually broad list of functions, including GMT, a split-seconds chronograph, perpetual calendar, moon phase, sunrise and sunset times, an alarm, and a travel translation mode; it has no smartphone connection. Each of its two colors is limited to 1,000 pieces.
The Girard-Perregaux Laureato Chronograph Williams Edition supplies the clearest everyday-use data in the table: its automatic GP03300 movement has 45 jewels and a 46-hour power reserve, while the watch has 100m water resistance. Its listed price is $20,900. Because prices are reported for only the Vacheron Constantin and Girard-Perregaux watches here, the table cannot support a complete price ranking across the best watches released in September 2026.
Choosing Between the September 2026 Releases
Choosing Between the September 2026 Releases
These five September releases are aimed at distinctly different kinds of collectors. The useful comparison is not a simple ranking, but a choice between specialized chronograph engineering, historical calendar design, a perpetual-calendar sports watch, a conventional automatic chronograph, and a digital-hybrid display. Price comparison is supported only for the Vacheron Constantin Overseas and Girard-Perregaux Laureato. The remaining watches are better assessed through their complications, materials, dimensions, and intended role rather than through assumed market positions.
For the collector who wants the most specialized chronograph
A. Lange & Söhne’s TRIPLE SPLIT is the clearest choice when mechanical complexity and limited production take priority. This edition is limited to 100 pieces, with a 950-platinum case, a rhodié-coloured dial, grey auxiliary dials, and a dark-brown alligator leather strap with a platinum deployant buckle.
Its L132.1 manufacture calibre contains 567 components and provides a 55-hour power reserve, with an indication showing how much reserve remains. The split-seconds chronograph is described as capable of measuring intermediate, comparative, and overall times for as long as 12 hours. A sapphire-crystal caseback provides a view of the chronograph movement. Those features make the TRIPLE SPLIT a strong fit for a collector interested in the construction and capabilities of a highly specialized mechanical chronograph.
The trade-off is its physical scale. The platinum case measures 43.2mm in diameter and 15.6mm in height. That makes its dimensions a central part of the decision: it suits someone comfortable with a substantial case more readily than a collection built around restrained proportions. The cited information does not establish a price for this comparison, so the watch should not be placed among these releases through an unsupported cost ranking.
For historical character and an annual calendar
Rolex’s Perpetual Padellone takes a more historically explicit route. It is inspired by Rolex’s late-1940s reference 8171 and combines a 39mm case with an instantaneous annual calendar showing the day, month, and date. Its blue enamel moonphase disc uses moons cut from meteorite.
The watch also uses Rolex’s patented Haplos system and the new 5Hz calibre 7190. That combination gives the Padellone a clear identity for a collector who values vintage design reference points, traditional calendar indications, and a contemporary high-frequency movement. Its appeal therefore rests on the relationship between historical character and modern mechanics, not on an assumed price position; no price is established in the cited information.
For a perpetual calendar in a sports-watch format
The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Azure Dial is the most direct choice for a collector who wants a perpetual calendar within the Overseas design language. The model is described as a luxury sports watch that prioritizes thinness and traditional complication watchmaking.
Its stated water resistance is 50m, and the cited description lists three bracelets: one in white gold and two in rubber. That configuration gives the watch a different emphasis from the Padellone: the Overseas pairs its calendar complication with a bracelet-and-rubber-strap setup and a sports-watch format. The listed price is $132,000. The available information does not establish whether that figure applies to every configuration, so it should be treated as a listed price rather than a statement about availability or future value.
For a conventional automatic chronograph
Girard-Perregaux’s Laureato Chronograph Williams Edition 42mm is the more straightforward option for a collector who wants an automatic chronograph rather than a calendar complication. It uses the automatic Girard-Perregaux calibre GP03300 and has 100m of water resistance.
Its role is consequently easier to define: a 42mm Laureato with conventional chronograph functionality and a stronger stated water-resistance figure than the Overseas. The listed price is $20,900. That is the only price in this comparison that can be placed directly alongside the Overseas figure. The two prices establish the cited listings, but not availability or future market value.
For maximum information density and an unconventional display
H. Moser & Cie.’s Off-Grid is the outlier among the five. It is a hybrid digital watch with a skeletonized dial and a 42.6mm steel case. Its functions include GMT, a split-seconds chronograph, perpetual calendar, moon phase, sunrise and sunset times, an alarm, and a travel translation mode. It has no smartphone connection.
This is the logical choice for a collector who values breadth of information and an unusual interface over a conventional analog layout. The case size gives the watch a substantial stated diameter, while the absence of smartphone connection defines the concept as an independent device rather than a connected watch. No price is established in the cited information, so its place among these releases should be judged by its functions, digital-hybrid construction, and dimensions rather than by an assumed market position.
In short, the TRIPLE SPLIT is the specialist choice for split-seconds chronograph mechanics and limited production. The Padellone suits a collector drawn to historical character and an annual calendar, while the Overseas combines a perpetual calendar with a luxury sports-watch format. The Laureato is the clearest conventional automatic chronograph, and the Off-Grid is aimed at those who want an unusually broad set of indications in a hybrid display. Only the Overseas and Laureato have cited prices here; for the other releases, complications, construction, size, and design priorities provide the more reliable basis for choosing.

Final Thoughts on September 2026’s Best New Watches
Final Thoughts on September 2026’s Best New Watches
The five watches divide the month’s highlights by purpose rather than by a single measure of quality. For collectors drawn to rare mechanics, A. Lange & Söhne’s TRIPLE SPLIT is the most clearly defined proposition: its split-seconds chronograph can measure intermediate, comparative, and overall times for up to twelve hours. The edition is limited to 100 pieces and uses a 950 platinum case. Those qualities make it the natural choice for a buyer who values mechanical complexity and limited production above uncomplicated daily use.
Rolex’s Perpetual Padellone instead makes historical calendar design its central appeal. The watch draws inspiration from the late-1940s reference 8171 and combines a day, month, and date display with a blue enamel moon-phase disc and meteorite moons. Its instantaneous annual calendar uses the patented Haplos system and the new 5Hz calibre 7190. The result is a watch for buyers who want familiar calendar indications presented through a design with a clear historical reference and a contemporary movement.
Vacheron Constantin’s Overseas Perpetual Calendar Ultra-Thin represents a different category within the selection: the luxury-sports perpetual calendar identified by its Azure Dial name. The available description does not establish a broader basis for ranking it against the other watches, so its appeal should be considered on that defined combination of model, collection, and complication rather than on an assumed advantage. H. Moser & Cie.’s Off-Grid is more expansive in function. Its 42.6mm steel Streamliner-style case houses a hybrid digital format with GMT, a split-seconds chronograph, a perpetual calendar, moon phase, sunrise and sunset times, an alarm, and a travel translation mode; it has no smartphone connection. That range suits buyers who prefer an unusual watch that gathers many functions into one design.
Girard-Perregaux’s Laureato Chronograph Williams Edition 42mm is the most familiar proposition in the group: a chronograph within the established Laureato line. It therefore fits a buyer looking for a recognizable sports-watch setting for a timing function. Taken together, the best watches released in September 2026 separate five priorities: rarity and mechanical complexity point toward the TRIPLE SPLIT; calendar history toward the Perpetual Padellone; the Overseas toward a luxury-sports perpetual calendar; broad, unconventional functionality toward the Off-Grid; and a straightforward chronograph format toward the Laureato. The strongest choice depends on the purpose of the purchase, not on a universal ranking.
