The watch keeps good time. The chrono function runs, but sometimes does not reset to zero. You can restore the second hand to 12/zero by starting the chrono, stopping it at 12/zero, and then pressing the reset button. The second hand will remain at 12/zero. It will also usually reset after a subsequent run, though this is not guaranteed. I am not the original owner and have no knowledge regarding whether all parts are original or if the watch contains aftermarket parts. I assume it has some aftermarket parts, as the crystal is in excellent condition and likely a replacement. I have no knowledge of when or if it has ever been serviced. The watch comes with both a bracelet and a leather strap. The bracelet is not original but is a newish aftermarket bracelet appropriate to the era. The leather strap is a nice, heavy leather with cream-colored contrast stitching and will fit an 8-inch wrist.
