Approximately 3.0cm wide (including the crown). This is a listing for a Seiko Tomony Mechanical (hand-wound) ladies' watch. It's a rare "TOMONY" design that you don't see often, and the size is such that it could be worn unisex. *The image of the watch being worn is by a man. There may be minor scratches and clear marks from use and storage, including on the glass surface, but as you can see, it's in good condition and looks clean. Please take a close look at the images (there is a reflection of fluorescent light). The strap has been replaced with an aftermarket leather strap that matches the color of the dial, but it is a used leather strap, so it is treated as an extra and not part of the evaluation. As it is a used hand-wound watch, there is no guarantee of future operation, but it is running without major errors. Also, it winds properly with the hand-winding screw (crown) and does not stop immediately... *We do not perform any maintenance such as OH (overhaul)... so please understand that the condition may change in the future* There is always risk involved. It is an old antique hand-wound watch, so I think you can enjoy it if you use it with an open mind. There are no accessories. I am very sorry, but please do not buy this if you are not used to used items, are nervous, do not understand the meaning of the words or the above explanation, or have any concerns. Mercari is a place for private sales. It is a used item in its current condition and is inspected by an amateur (100% perfection is absolutely impossible... the condition in the image is everything), so please understand. It is a classic Seiko Tomony antique watch ☺︎ Please add it to your proud collection... This item is not subject to price reduction. #Seiko #SEIKO #SeikoSchoolTime #SEIKOSCHOOLTIME #SCHOOLTIME #SeikoHandWoundWatch #HandWoundWatch #MechanicalWatch #SeikoTomony #Tomony #SeikoMechanical Movement: Hand-wound
