【Exterior Cleaned / As-Is】CITIZEN Promaster Eco-Drive Divers (2006 Model) Thank you for looking! This is a genuine diver's watch from Citizen, the "Promaster MARINE Eco-Drive AIR DIVER'S 200M" (estimated model number: PMA56-2921). It is currently in working condition, but it is being sold as an "as-is" item due to a missing belt pin and corrosion on the case back. The **exterior has been cleaned and polished** for this listing, so you can start working on repairs or customization (such as replacing with a NATO strap) immediately upon arrival! 【Model and Era Details】 Brand: CITIZEN Series: PROMASTER MARINE AIR DIVER'S 200M Model/Caliber: PMA56-2921 (Estimated) / Cal.E168 Features: Equipped with Citizen's renowned "Cal.E168 (solar-powered)" movement, which continues to be used in Citizen divers today and is highly reliable. The navy dial, reminiscent of the sea, is paired with highly legible Arabic numeral indices, creating a rugged design unique to the 2000s that blends military and retro aesthetics. 【Product Details】 Strap (※Important): The pins connecting the links of the strap are missing, and the strap is currently detached midway. For use, you will need to have pins installed by a watch shop or replace it with a different strap of your choice (that fits the lug width). Case Back (※Important): There is significant corrosion overall (plating peeling, rough texture resembling rust marks), making the engravings very difficult to read. (See photos) Case/Bezel: Numerous scuffs, minor scratches, and dents from normal use are visible. The bezel rotates. Operating Status: The second hand is currently running, but long-term operation, accuracy, and waterproof testing (including checking the condition of the gaskets) have not been performed. If it stops upon arrival due to insufficient charge, please expose it to direct sunlight to charge it. 【Notes】 Due to the condition described above, please consider this item as "junk, for repair, for parts, or as a base for customization," sold as-is.
