La Joux-Perret L1C0

The LJP L1C0 is a sophisticated bi-compax chronograph featuring dual retrograde displays - a 30-second retrograde running seconds indicator on the left and a retrograde date display on the right, both operating on 120-degree arcs. Central chronograph seconds hand with 30-minute counter at 12 and 12-hour counter at 6. The retrograde complications add visual drama and horological complexity. Higher jewel count (28 automatic, 26 manual) compared to other L-series calibers due to the additional retrograde mechanisms. Column wheel operation. 60-hour power reserve. Represents La Joux-Perret's haute horlogerie capabilities within the chronograph family.
