Approximately 3.6cm wide. This is a Seiko SQ antique quartz men's watch for sale. It's a cool piece with a classic design ☺︎ There may be minor scratches and clear marks on various parts, including the glass surface, due to use, but I don't think there are any severe damages that would obstruct the view. Please enlarge the images and take a close look. The belt is the original genuine stainless steel belt, and the wrist circumference is about 17.5cm. I cannot guarantee the performance, but I replaced the battery with a new one a while ago, and it is currently working without any problems (I have only replaced the battery and have not done any maintenance such as overhaul). By the way, the crown operation and quick change are also fine at present (the calendar day of the week is in English and Arabic). There are no accessories... This is just an old, used quartz watch... Please consider purchasing if you understand used items. If you don't understand the above explanation, are uneasy, are not used to used items, are nervous, or don't understand the meaning of the words, please, please, please do not buy it. Mercari is a place for private sales. Please understand that this is a used, as-is item, and a layman's inspection (there is no 100% guarantee), so please understand. This is a SEIKO SQ that doesn't choose the scene. Please make it your prized possession... #Seiko #SEIKO #SeikoDolce #SEIKODOLCE #DOLCE #GrandSeiko #GRANDSEIKO #GrandQuartz #KingQuartz #SeikoCredor #Credor #SeikoEmblem #RoadQuartz #TypeII #SeikoQuartz #Men'sWatch #SeikoChronos #SEIKOChronos #SeikoSQ #SEIKOSQ Movement: Quartz (battery-powered) Accessories: None
