In addition to the conventional hour, minute and seconds hands, the 3187 features a 24-hour hand to display a second time zone. This movement is fitted with a Parachrom hairspring and Paraflex shock absorbers, offering greater resistance to shocks and to extreme conditions. Like all Rolex Perpetual movements, the 3187 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
|Time:||Additional 24 Hour Hand (adjustable), Hours, Minutes, Seconds|
The 2011 introduction of the Rolex Explorer II 216570 marked the return of the orange 24h 'Freccione' hand.
