Diameter: Approximately 3.6cm. This is a Citizen Diver 200M Quartz men's watch. It's a rare diver watch that you don't see often, and the mint green bezel is eye-catching ☺︎ There may be minor scratches and clear marks from use on the bezel, but it's in good condition for practical use (the protective sticker on the back cover is still attached). Please take a close look at the images... The belt has been replaced with a high-quality Seiko genuine urethane diver belt (new). This is a privately owned watch, so I cannot guarantee its operation, but I recently had the battery replaced (battery replacement only) and it is working without any problems. The unidirectional rotating bezel (clicks nicely) and the screw-down crown, and crown operation are all fine at present. No accessories included. I am very sorry, but please do not purchase this if you are not familiar with used items, are overly sensitive, or do not understand the above explanation or have any concerns. Mercari is a platform for private transactions. This is a used item in its current condition, and it has been inspected by an amateur (there is no 100% perfection), so please understand. This is a rare Citizen Diver 200M Quartz men's watch. Please make it a treasured item... ※※ I will ignore and delete any discount requests or unreasonable price negotiations that use the standard Mercari template without a price offer. Also, please refrain from unnecessary "likes" (they are a factor in withdrawal). #Seiko #SEIKO #SeikoDiver #SeikoDivers #SeikoSQ #SEIKOSQ #SeikoSQDiver #DiverWatch #ImportWatch #DiversWatch #SeikoProspex #SeikoProfessional #SeikoLadiesDiver #SeikoDiver150m #SEIKODiver #SeikoScuba200m #SeikoScuba #SEIKOSCUBA200m #SEIKOSCUBA #PROFESSIONAL #SEIKOPROFESSIONAL #AlbaDiver #SeikoAlba #SEIKOALBA #SEIKOALBA100m #CITIZEN #Citizen #CITIZENDIVER #CitizenDiver #CITIZENOXY #CitizenOxy #CitizenOxySports #CITIZENOXYSPORTS #CitizenOxyVega #CitizenVega #CITIZENOXYVEGA #CitizenDiver200m #CitizenPromaster
