Vintage Gold Tone 1970s Sheffield Instantime Jump Hour - Runs and stops For Sale

Vintage gold-tone Sheffield Instantime Jump Hour from the 1970s. It features a jump hour (which shows hours and minutes) and a date complication with a running seconds hand. The watch does run for a bit when shaken, but it will need a service to run well again. The movement is a 1 jewel Swiss pin pallet movement, which is clean and shows no sign of rust/corrosion. The case has some wear to it, and the crown is difficult to turn, but both should polish up nicely. The balance seems to be in good condition, and I suspect that the primary issue is a much-needed mainspring cleaning. I have many other project watches to work on, and it's a shame, but I just don't have time for this one, so I hope this watch will be a good restoration project for someone else.
Case specs:18mm strap, 11mm thickness, 36mm width, and 39mm lengthPlease feel free to ask me any questions and/or shoot me an offer.
