The Rolex Oyster Perpetual 31mm Ref 177200-0019 has a unique blend of features that make this a perfect timepiece for any occasion. To begin with, the black dial looks stunning against the polished Oystersteel case and 18 ct gold hour markers with luminescence.
This timepiece could easily pass for a dress watch in any circumstance. But its superalloy 904L steel gives it resistance to corrosion. And it has a twinlock double waterproofness system that gives it resistance to 330 feet of water. The sapphire crystal glass protects from scratches and the Oystersteel bracelet with Oysterclasp gives it strength and durability.
One of the unique features is that this is a 31 mm timepiece. This is much smaller in size and far lighter than their larger 39mm through 44mm timepieces. The black dial allows this to be a truly unisex model which symbolizes the timeless classic style that makes Rolex a “Rolex.”
The Ref 177200-0019 is powered by a calibre 2231 self-winding mechanical movement entirely developed and manufactured by Rolex. The 2231 is a certified Swiss chronometer, a designation reserved for high-precision watches that are extremely reliable and have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The caliber 2231 provides 48 hours of power reserve.
Rubber B has developed 7 bands for the Rolex Oyster Perpetual 31mm Reference 177200-0019. This allows the Rolex owner to have the comfort of wearing a water resistant and strong Vulcanized rubber band which is great for swimming and athletics. Yet it has an exquisite look and is stylish, and has many colors to fit personality or fashion.
Rubber B bands are all made in Switzerland and are precisely calibrated to fit the Rolex Oyster Perpetual 31mm case (16mm Lug Space ONLY) and Datejust 31mm (16mm Lug Space ONLY). This strap utilizes “Blocked Integration” engineering, incorporating solid inserts for a flawless, motionless flush mount to the Oyster Perpetual 31mm case. No coating, blends or bonding were used in the production process, preventing bleeding and protecting the stylish color and look and durability of the Rubber B strap. Each strap has a tang buckle for easy adjustment and a comfortable fit. For more information on the Rubber B straps for the Rolex Oyster Perpetual 31mm, go to our page here.
