Rolex Sea-Dweller copy watches with black bezels are carried with Cal.3135, self-winding mechanical movements that are certified by COSC. The excellent movements can make watches accurate to the error within 2 seconds every day and can save about 48-hour power. The watches have 44mm steel cases. The hour markers are white luminescent indexes. Their hour and minute hands are also covered with white luminescence.
The strongest function is their waterproofness. The new Deepsea watches can be waterproof to 3,900m that is very remarkable. Rolex designers make some improvements for the materials to achieve the outstanding function. The case backs are made of 5-level titanium alloy and the watches are equipped with gas escape valves that can help to keep the pressure balance during the diving activities. The unidirectional rotating black bezels are engraved with 60-minute platinum graduated scales.
Rolex 116660 replica watches with automatic mechanical movements have steel winding crowns of triple waterproofness systems. Their scratch-resistant and anti-reflective sapphire glasses are used to protect the delicate dials. Rolex not only makes good-quality watches, but also keeps moving forward.
