Keeping good time. I have run the chrono portion and it runs but sometimes does not reset to zero. You can restore the 2nd hand to 12/zero by starting the chrono, stopping the chrono at 12/zero, and then pressing the reset button. The 2nd hand will remain at 12/zero. It will also usually reset after a subsequent run. However, it is not guaranteed or warranted. I am not the original owner. I have no knowledge regarding whether all parts are original or whether the watch may contain aftermarket parts .... I assume it contains some aftermarket parts (the crystal is excellent so I assume it is a replacement). I have no knowledge of when/if it has ever been serviced. Comes with a bracelet and a leather strap. The bracelet is not original but is a newish aftermarket bracelet that is appropriate to the era. The watch strap is a nice heavy leather strap with cream colored contrast stitching and it will fit an 8 inch wrist.
