Rolex caliber 3186
|Hands:||Hours, Minutes, Seconds, Additional 24 Hour Hand (adjustable)|
Calibre 3186 is a self-winding mechanical movement entirely developed and manufactured by Rolex. In
addition to the conventional hour, minute and seconds hands, it features a 24-hour hand to display a second time zone.
Like all Rolex Perpetual movements, the 3186 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute
The 3186 is equipped with a Parachrom hairspring, offering greater resistance to shocks and to temperature variations. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
