LEMANIA, founded in 1884, used to be a Swiss watch company and high-end movement manufacturer. During its heydays, especially LEMANIA chronograph calibres were treated like ‘first options come to mind’ of many top-tier Swiss manufactures such as PATEK PHILIPPE, VACHERON CONSTANTIN, OMEGA and BREGUET to name a few.
What was captured here is one of LEMANIA’s creations, the calibre 1872, disguising under the name calibre 8381-423 of GIRARD-PERREGAUX. This is a manual-winding chronograph movement adjusted to meet GP’s standard, with:
⁃ 17 jewels
⁃ 21600 vibrations per hour
⁃ 27.5 wide and 5.7 mm thin
⁃ 48 hour power reserve
The typical layout has a central chronograph hand and two sub-dials: one for the non-hacking running seconds at 9 o’clock and the other 30 minute counter at 3. The current movement in the photos is operating impeccably with +- 2 seconds/day, the amplitude is 298 degrees and beat error is 0.1 ms.
