Vostok Komandirskie, one of the best mechanical bang for the bucks out there. Rarely if ever worn. I am original owner. When I got it, was about -45 seconds a day, and I was able to regulate it to around +/- 10 to 15s a day, YMMV as it has not been worn for some time, hence the sale. I am at 35+ watches and need to downsize before another long international trip. On an aftermarket 18mm bracelet, which lets face it, is MUCH better than stock ANYTHING from Vostok. Sized loosely for my 7.5" wrist, I may or may not have extra links but I can confidently say it will fit most people. $55 shipped CONUS, Paypal FF or Zelle please.
