Calibre 5100 is an automatic chronograph movement by Lemania.

Specifications

Introduced in 1974, Cal. 5100 followed closely after the introduction of Lemania's similar Cal. 1340 family. Like that movement, it features an unusual arrangement of chronograph counters:

  • Center hour and minute hands, chronograph seconds, and 60 minute chronograph totaliser
  • 12-hour totaliser at 6:00
  • Small seconds at 9:00
  • 24 hour hand at 12:00
  • Day and date windows at 3:00

It has 17 jewels, hacking seconds, and power reserve ca. 48 hours. Omega used Cal. 5100 as their Cal. 1045.

Cal. 5100's predecessor, Cal. 1340, was refreshed and re-launched as a successor, Cal. 1350, in 1994.

The Lemania 5100 has in later years been produced as the ETA C01.211.
