Approximately 4.2cm wide. This is a rather rare and cool watch ☺︎ Up for sale is an ORCA Alarm Chronograph Outdoor Sports Quartz Men's Watch, 15BAR. As you can see in the images, the movement is a high-quality watch made by Morioka Seiko ☺︎ There may be minor scratches from use, including on the glass surface, but as you can see, it's in pretty good condition. Please examine the images carefully. The belt is a non-original mesh stainless steel belt that fits any size. While I cannot guarantee future operation, I replaced the battery a few months ago, and it's working fine (battery replacement only). The crown operation, screw-down action, rotating bezel (with a satisfying clicking sound), and button response (digital display) are also currently working. ※ This is a multi-function watch, and I do not know the detailed operating functions, so please be aware of this. It's a nice, clean item, but it's used. Please consider purchasing if you understand that it is a used item. If you are not used to buying used items, are overly sensitive, or do not understand the above explanation, or are unsure, please absolutely, absolutely, absolutely do not buy it. Mercari is a place for private sales. It is a used item in its current condition, and it is a layman's inspection (there is no 100% guarantee), so please understand this. There are no accessories. It's a cool watch! ※※ I will ignore and delete discount requests and unreasonable price negotiations that do not include a price offer, using the standard Mercari template. #Seiko #SEIKO #SeikoDiver #SeikoDivers #SeikoSQ #SEIKOSQ #SeikoSQDiver #DiverWatch #ImportWatch #DiversWatch #SeikoProspex #SeikoProfessional #SeikoLadiesDiver #SeikoDiver150m #SEIKODiver #SeikoScuba200m #SeikoScuba #SEIKOSCUBA200m #SEIKOSCUBA #PROFESSIONAL #SEIKOPROFESSIONAL #ALBASCUBA200mAIRDIVER #DiverScuba #SeikoAlbaCaliber #CaribbeanAlarmChronograph #SeikoChronograph #SEIKOchronograph #ORCAAlarmChronograph #ORCAALARMCHRONOGRAPH #MoriokaSeiko
