I have this in a Luminox watch and it has lasted 14 years so far with daily wear and heavy abuse. Great reliability!

The ‘Lucien Rochat’ brand offers a couple of models in its ‘Lunel’ (chronograph) line; one claims to have a Ronda Cal. 5020.B, another a Ronda Cal. 5050.B (13 Jewels, gold-plated). For these two, it claims to be “Swiss Made” (on the back-cover).
