Sadly, for those who appreciate the movement, it's period of production was far too short-lived. Though built to economy, the Lemania 5100 (not unlike the Valjoux/ETA 7750) has proven to be a durable, reliable and accurate movement. The advantage over the 7750 is the direct reading of elapsed minutes with the central Chrono sweep hands. Reads like a clock but in minutes and seconds instead of hours and minutes. Combined with the white-on-black dial and the elapsed time bezel, this particular Hamilton is one of the most useful, easy-to-read chronographs I have seen.
Congrats on being the caretaker!
