Today, we will be introducing our top 5 recommendations for models with small case sizes that are a must-see for those with slim wrists (2025 edition) .
When considering buying a watch, many people may have worried about whether the size will fit their wrist or body type. Large case sizes are becoming more popular, but many Japanese people, especially, have thin wrists, and the moment they actually hold the watch in their hands, they may have felt, "I couldn't tell from the photo, but this watch seems a little big..."
This time, we will introduce five carefully selected models with small case sizes that we recommend for people with thin wrists. Please come and experience the true appeal that cannot be conveyed by photos alone !

① [Rolex] Explorer 36 "Ref. 124270"
The Explorer 36 "Ref. 124270" was released as a new model in 2021.
Until this model was released, the current model of the Explorer was the Ref. 214270, which had a 39mm case, but in 2021 it was changed to the Ref. 124270. Speaking of the Explorer, many people were delighted to see that it had returned to a 36mm case. The highly visible design, with Arabic numerals 3, 6, and 9 on the black dial, is simple yet has a universal appeal. The compact size of the case diameter of 36mm x thickness of 11.5mm makes it comfortable on the wrist and is a versatile piece that can be worn with both formal and casual wear. The movement is equipped with the Cal. 3230, which has a power reserve of approximately 70 hours, making it a complete timepiece that combines practicality and durability .
② [A. Lange & Söhne] "1815" "Ref. 235.026"

The collection name "1815" is the year of birth of the brand's founder, Adolf Lange.
This model is very attractive with its silver dial with highly visible Arabic numerals and railroad minutes, and its beautiful blue steel hands. The back cover is a see-through case back, allowing you to view the hand-wound movement "Cal.L051.1". The beautiful movement finish with Glashütte stripes and hand engraving is one of the highlights of the craftsmanship. Furthermore, it has a power reserve of approximately 55 hours, making it highly practical.
The 38.5mm size is neither too big nor too small, and has an exquisite balance that blends naturally into any scene. Combining refinement and elegance, it is one of the ultimate dress watches that can be used both on and off the job .
3. [Patek Philippe] "Calatrava" "Ref. 5196P-001"
The "Calatrava" Ref. 5196P-001 features a platinum case.
This model features leaf hands, Breguet numerals applied indexes, and a small second hand on the dial, reminiscent of the Ref. 570 released around 1940. The platinum case is one of the least common among the Calatrava Ref. 5196 models, and the diamond setting on the side of the case at 6 o'clock is a unique feature of the platinum case. The combination of the simple design and the rare platinum case sets this model apart from other Calatravas. This is a rare piece that is rarely seen on the second-hand market, so it is highly recommended for those looking for a sophisticated dress watch .
④ [Patek Philippe] "World Time" "Ref. 5110R-001"
The 37mm case "World Time" "Ref. 5110R-001" is still very popular even though it is no longer in production.
Modern world time watches are divided into the first generation "Ref.5110" 37mm, the second generation "Ref.5130" 39.5mm, and the third generation "Ref.5230" 38.5mm, but the "Ref.5110", which features the smallest case of all the models, was released in 2000. The small 37mm case fits comfortably on the wrist, and the center of the dial is a classical model with guilloche engraving. The outer periphery of the dial features "city name discs" of 24 cities around the world and a "24-hour display rotating disc", and by pressing the push button at the 10 o'clock position, the time can be easily adjusted in conjunction with the hour hand. The automatic movement "Cal.240 HU" is thin yet highly accurate, and the beautifully finished movement can be viewed through the sapphire crystal case back.
The "Ref.5110" series is available in rose gold, white gold, yellow gold, and platinum case materials, and is one of the most popular models among modern world time watches. It is the perfect choice for those looking for a dress watch with a smaller size that is different from others .
⑤ [Audemars Piguet] "Royal Oak" "Ref.15550ST.OO.1356ST.02"
The Audemars Piguet Royal Oak Ref. 15550ST.OO.1356ST.02 was launched in 2022 to commemorate the 50th anniversary of the Royal Oak.
This model follows the design of the original Royal Oak, which was born in 1972, and is available in a compact 37mm case. The distinctive night blue dial is combined with Cloud 50's "tapestry dial", and the design highlights the three-dimensional effect of the unevenness of the tapestry when reflected by light. This model was created to commemorate the 50th anniversary of the Royal Oak, and the see-through skeleton back allows you to see the "Cal. 5900" equipped with a special 50th anniversary rotor. As a change from the previous model "Ref. 15450ST", the "AP logo" at 12 o'clock on the dial and the "AUTOMATIC" notation at 6 o'clock have been eliminated, resulting in a clean and highly visible design. Compared to the 41mm Royal Oak, it is a very compact size that is easy to wear on Japanese wrists, so it seems that there are many people looking for it. If you want a sporty and eye-catching watch but prefer a small size, this is a watch that I can confidently recommend .
