This is spares/ repairs. I have fitted a battery and it’s not moving. I took it to a watch shop and said it needs a service which would fix the watch. Genuine strap though it is well worn There are faint marks on the metal but these are magnified by the camera and light for photo purposes. In person they are not so noticeable. The same watch is up at £480 on eBay so this is a bargain for someone with the interest and time for it.
