Diameter: Approximately 3.4cm. This is a Citizen Oxy Vega Sports Quartz men's watch for sale. It's a diver-design sports watch that can be used by both men and women ☺︎ There are some minor scratches and clear marks from use, including on the glass surface, but it's in good condition for practical use. Please take a close look at the images... The strap is a third-party urethane strap. This is a privately owned watch, so I cannot guarantee its operation, but I recently had the battery replaced (battery replacement only) and it's working without any problems. The rotating bezel and crown operation are also fine at present. There are no accessories. I am very sorry, but please absolutely do not purchase this item if you are not accustomed to used items, are overly sensitive, do not understand the above explanation, or are feeling anxious. Mercari is a platform for private sales. 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. It's a lightweight and cool Citizen Oxy Vega Sports men's watch. Please make it a treasured item... ※ This item is not subject to price reduction. #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 Movement: Quartz (battery-powered) Accessories: None Dial Color: Black Strap Color: Black
