with your Longines HydroConquest
Smartlet is compatible with the Longines HydroConquest. Lug width: 18mm / 19mm / 21mm / 22mm - natively supported with no adapter. Installation uses the standard spring-bar system. No modification to the watch required. Fully reversible in seconds.
The HydroConquest is Longines at its most direct. Swiss manufacture movement, 300m water resistance, ceramic bezel, and a price that remains justifiable. The L888 calibre - developed in-house at Saint-Imier - runs at 25,200 vibrations per hour with 64 hours of power reserve. The 41mm in ceramic black or blue bezel has become one of the most recommended entry-level Swiss dive watches on the market. The recommendation holds because the watch delivers. Smartlet completes it.Referencias incluidas
