La Joux-Perret L100

The L100 is an automatic integrated chronograph with a column-wheel escapement, manufactured by La Joux-Perret and introduced in 2020. It delivers a 60-hour power reserve and maintains dimensional compatibility with the widely used ETA 7750 and Sellita SW500 platforms. The movement represents La Joux-Perret's in-house chronograph architecture within their revised 2020 lineup. It remains in production.
