Watch perfect for use as I have, namely a hyper active, never a scratch, no risk level sealing, a time that works perfectly, good power reserve, worn for 2 years without worries. Hardly afraid, neither mechanical nor handling or the horrors of daily life, and can even dive (implementation system on the combination present in Deployant buckle) as such the Deployant buckle is thick, which avoids deformation over time and recurrent closure problems to other models.
