In 2025, Tudor launched new smaller-sized, sporty models, including the 37mm Black Bay 54 and the 36mm Ranger. Combined with the previously released 38mm Royal series, Tudor now offers a full range of sizes from 36mm to 38mm, covering styles from mountaineering and diving watches to luxury sports watches.
The latest 36mm Ranger model was released in the second half of 2025. This timepiece, with its refined size, pays homage to historical models and current trends. Looking back at the development of the Tudor Ranger series, a reduction in size has been one of its evolutionary trends. The series has now been adjusted from the 41mm of the initial 2024 model to 39mm, and in 2025, an even more refined 36mm version was introduced. The new 36mm Ranger model is not an updated version of the 39mm model. Both sizes of the Ranger watch are currently available, catering to the needs of different customers. Also introduced with the new model is a sand-colored white dial. This slightly yellowish, off-white dial gives a soft visual impression and has a strong vintage feel.
The 36mm model can be considered a proportionally scaled-down version of the previous 39mm model. The only difference in specifications is that the 36mm model is equipped with the MT5400 movement (the 39mm model uses the MT5402). This movement has a diameter of 26mm, making it more suitable for smaller watch cases. In terms of performance, the MT5400 movement has a frequency of 28,800 vibrations per hour, features a silicon balance spring and a free-sprung balance wheel with micro-adjustment weights, boasts a 70-hour power reserve, and is certified by the Swiss Official Chronometer Testing Institute (COSC).
At 37mm, the Black Bay 54 is a prime example of this size. As an important branch of the Black Bay series, the Black Bay 54's name is derived from Tudor's first dive watch, the Ref. 7922, released in 1954, and it maintains the same 37mm case diameter as the historical model. It's important to note that although the series name and watch size have historical roots, the Black Bay 54 is not a replica of the Ref. 7922; it features numerous design changes and incorporates modern elements. In 2025, the Black Bay 54 series will add a new model with a stainless steel bezel. This model also retains the 37mm case diameter, with a polished stainless steel bezel and brushed hour markers. The interplay of these two finishes highlights its refined aesthetic. The best Tudor replica watches at captainthewatch.is.
Strictly speaking, 38mm is no longer considered a "small size," and many types of watches use this size. However, if we add the constraint of "sports watch," the Royal series (38mm) is undoubtedly the most suitable choice. The Tudor Royal series is a large product family, and in addition to the 38mm model, the series also offers 28mm, 34mm, and 41mm options. The 38mm model is the "just right" golden size, achieving an excellent balance in many aspects. The Tudor Royal 38mm model features a date function, with the date window located at the 3 o'clock position on the dial. Combining design elements such as a fluted bezel, sunray dial, and applied metal Roman numeral hour markers, it offers a touch of elegance alongside its sporty character. This model is powered by the Tudor T601 movement, a modified version of the Sellita SW200-1, retaining nearly identical specifications to the original movement, including a diameter of 25.6 mm, 25 jewels, and a power reserve of approximately 38 hours.
