⌚ IMPORTANT INFORMATION ABOUT WATCHES (Please read before ordering)
These points are normal product specifications, not defects. Please check them carefully.
1️⃣ Radio-Controlled (Radio Wave / Solar Radio) Models
・Our watches are shipped from Japan and are made for the Japanese market.
・A radio-controlled watch sets the time automatically by receiving a radio time signal transmitter. Japan's transmitters cannot be received outside Japan and nearby areas.
・Outside Japan, the watch will NOT correct the time automatically. It works as a normal quartz watch.
・This is a specification of the model, not a malfunction. Almost all cases reported to us are this.
・How to use it in your country:
① Set the time by hand: use the crown or the buttons to set the hour and minute hands to your local time.
② Use the time-difference function: if the model has World Time or a time-zone (home city / UTC offset) setting, set your city or offset (+/- hours) as written in the manual.
③ Please check the setting method for your specific model yourself (manual, or the maker's official website), as the procedure is different for every model.
・If a manual reception function is used outside Japan, the watch may show a reception error. This is normal.
2️⃣ Solar (Light-Powered) Models
・The watch may arrive stopped or with a low charge, because it was in a dark box during storage and transport.
・Please place it under bright light (sunlight or a strong lamp) for several hours before use. Full charging can take one day or more.
・A stopped watch on arrival is usually only a low battery, not a defect.
3️⃣ Battery Quartz Models
・A new watch often contains a "monitor battery" for factory testing. Its life can be shorter than a normal battery.
・Battery replacement is normal maintenance for every watch. It is a user cost and is not treated as a defect.
4️⃣ Mechanical / Automatic Models
・Mechanical watches are not as accurate as quartz. A daily difference of about -20 to +40 seconds per day is within the maker's normal standard, depending on the model.
・An automatic watch stops when it is not worn. If it is stopped on arrival, please wind it or wear it to start. This is not a defect.
・Magnets (phones, speakers, magnetic bags) can affect accuracy.
5️⃣ Japanese Domestic Specifications
・The day-of-week disc may show Japanese characters (kanji/kana), or Japanese + English.
・The manual, warranty card and package are printed in Japanese.
・If the product includes an AC adapter or charger, it is made for Japan (100V, type A plug). A plug adapter or voltage converter may be needed in your country.
・For smartwatches / Bluetooth models: some apps, services or language settings may be limited to Japan.
6️⃣ Bracelet & Band Size
・Metal bracelets are shipped at the factory length. They are not adjusted for your wrist.
・Adjustment (removing links) must be done by you or a local watch shop. This is not a defect and the adjustment cost is not refundable.
7️⃣ Warranty
・The included maker's warranty card is for use inside Japan only, and international warranty service is generally not available.
・About water resistance: marks such as 3ATM / 30m do NOT mean the watch can be used for swimming, diving or a shower. Please check the maker's specification. Damage caused by water is not covered.
8️⃣ Appearance & Photos
・Condition: NEW. Every item is brand-new and unused.
・Photos are for reference. Real color can look slightly different depending on your screen.
・Brand-new items may have very small marks on the outer box from storage or transport. The product itself is checked before shipping.

Based on the specifications of the UDT (Underwater Demolition Team), a special unit of the U.S. Navy in the 1950s, this watch faithfully reproduces the military specifications of the time, featuring a large crown cap with a gasket inside. The case diameter has been updated to 36mm (excluding the crown). The case and case back are made of 316L stainless steel. The crystal is a reproduction acrylic dome crystal for an antique look. Powered by a Swiss-made quartz movement, this watch is functionally durable and ready for modern use. The numerals, indexes, and hands on the dial are coated with LumiNova®, a luminous paint exclusively approved for use on Swiss-made watches, providing enhanced luminous time and brightness compared to standard luminous watches. Its water resistance of 5 ATM makes it suitable for everyday wet work and other tasks.
