Last week, we presented the first part of the video on timekeeping accuracy by our Man In Paris, David Chokron. In this second part and conclusion, David takes us through his week with seven watches on the wrist and brings us his final results — which keeps the best time after seven days of daily activity. Just to recap, the watches are: an Omega Seamaster, a Jaeger-LeCoultre tourbillon, a Roger Dubuis double tourbillon, a Franck Muller tourbillon, a Zenith Espada, an H. Moser Monard, and David’s own 35-year-old Rolex.

Catch up with the story so far here and then watch part two below! Did you manage to guess the final result?

* This video in no way seeks to be a guide to chronometric performance in market-available timepieces, timekeeping accuracy being a quite separate issue from what governs timepiece chronometry (ie, isochronism in the regulating organ).
