Five new small-diameter watches that offer a variety of ways to enjoy watches

　One of the recent trends in watches is the trend toward smaller case sizes. While there used to be a clear difference in size between large men's watches and small women's watches, various manufacturers have begun to release mid-size models that are somewhere in between.

　This trend continues into 2025, with a steady stream of masterpieces being released featuring cases of 38mm or less in diameter that are easy to wear for both men and women.

　This time, we will introduce five carefully selected watches. Now that we have entered an era where watches are genderless, why not take a look at these new models to find the perfect watch for you? Of course, they are also recommended as share watches to share with your partner.

Grand Seiko "Evolution 9 Collection Spring Drive UFA" Ref. SLGB003

　This simple three-hand Grand Seiko is equipped with the Cal. 9RB2, a new automatic Spring Drive movement that boasts incredible accuracy of ±20 seconds per year. It is still fresh in our memory as it won the Good Design Award in 2025.

　The pale blue dial features an intricately embossed pattern, reminiscent of the frost-covered trees that can be seen during the winter in the Shinshu region where Spring Drive is manufactured. At 6 o'clock, the UFA (Ultra Fine Accuracy) logo is proudly displayed.

　The case is made of bright titanium, which is lightweight, highly corrosion-resistant, and has a lustrous, aesthetic appeal. What's surprising is that it's significantly smaller in diameter than previous Spring Drive models, at 37mm. This is due to the Cal. 9RB2's adoption of a thin single barrel and a new offset magic lever, which has made it even smaller.

　Cal. 9RB2 is equipped with a speed adjustment function, a first for a Spring Drive movement, and also features a high-precision Spring Drive package IC, which consists of a carefully selected quartz oscillator and IC sealed in a vacuum package, giving it a mechanism that sets it apart from previous movements in the pursuit of precision.

Omega Seamaster Milano Cortina 2026, Ref. 522.53.37.20.04.001

　This special edition Seamaster commemorates the Milan-Cortina 2026 Winter Olympics, which will be held from February 6, 2026. Omega will serve as the official timekeeper for the event.

　While many current Seamaster models have a design reminiscent of a sports watch, this model features a dressier design inspired by heritage models. The white dial is made of Grand Feu enamel, and the 18K Moonshine Gold indexes are faceted for a brilliant shine.

　The case, featuring an iconic design with a round middle case, flat bezel, and sharply edged lugs, is crafted from 18K Moonshine gold. Its compact size of 37mm in diameter is appealing. It is fitted with a large, raised sapphire crystal that evokes a plastic crystal.

　The case back is engraved with the Milan-Cortina 2026 Winter Olympics emblem, enhancing the special edition feel. The movement is equipped with the automatic Cal. 8807, which has been certified as a Master Chronometer.

A. Lange & Söhne "1815" Ref. 220.028

　The 1815 collection, named after the year of the birth of founder Ferdinand Adolph Lange, is characterized by a dressy design that incorporates the design codes of pocket watches. A 34mm small seconds model has been added to the 1815 collection. The previous lineup had a diameter of 38.5mm, but this significant reduction in size offers an attractive option for men and women with slimmer wrists.

　The blue dial is made of 925 silver. Arabic numerals and a railway minute circle, symbolizing 1815, are printed on it, and the small second hand at 6 o'clock creates a three-dimensional effect.

　The round case is crafted from 18K pink gold. At just 6.4mm thick, it's an elegant size that fits easily under a shirt cuff without getting caught. It's water resistant to 3 ATM, making it perfect for everyday use.

　The movement is the hand-wound Cal. L152.1. Despite its slim design, it is made up of 171 components and boasts a power reserve of approximately 72 hours. The Glashütte-style finishing, including the engraved balance cock and three-quarter plate, can be admired through the see-through caseback.

Rolex Oyster Perpetual Land-Dweller 36, Ref. 127285TBR

　The Oyster Perpetual Land-Dweller is a new addition to the Rolex collection. It features a case with an integrated bracelet, giving it a significantly different appearance from the current collection.

　The dial features a honeycomb motif pattern. The date display is located at 3 o'clock, and the brand's signature Oyster logo is located at 12 o'clock. This jewelry model features a row of baguette-cut diamond indexes, creating a glamorous impression. The sharp case and flat jubilee bracelet are crafted from 18K Everose gold, a unique gold alloy that is resistant to tarnish.

　The watch's exterior is not the only feature. Inside, the Cal. 7135 movement is equipped with a new Dynapulse escapement and a Syloxi hairspring with excellent anti-magnetic properties. Unusually for a Rolex, it features a see-through case back, allowing you to view the Cal. 7135 in detail.

Bell & Ross BR-05 36mm Ice Blue Steel, Ref. BR05A-S-BU-ST/SST

　This compact 36mm model joins Bell & Ross' Urban Instrument watch collection, the BR-05. While retaining the same design of a round dial combined with a square case and bracelet, the size has been revised to make it more comfortable for both men and women.

　The dial is a refreshing ice blue. The sunray finish gives it an elegant impression. In addition to ice blue, it is also available in a wide range of colors, including black, silver, and mother-of-pearl. Rounded Arabic numerals at 3, 6, 9, and 12 o'clock, as well as bar indexes, ensure high visibility with clearly differentiated hour and minute hands. Another attractive feature is the clean design, as it does not have a date display.

　The case has a hairline finish with polished accents, giving it the look of a luxury sports watch. At just 8.5mm thick, it's easy to handle.
