The Oyster case was an innovation of its time when it was developed by Rolex in 1926. It ushered in a brand new era of durable, everyday watches that could be worn during almost any activity without damaging the internal movement. The Submariner takes the design of the Oyster case one step further and increased its waterproofness up to 300 meters/1,000 feet.The ref. 16613 features a standard 40mm case in highly corrosion-resistant 904L stainless steel. An 18 karat yellow gold screw-down crown and unidirectional bezel accompany the case, giving it a desirable two-tone design. The dial and bezel set are most commonly available in either black or blue, with some examples of the gem-set “Serti” dial (either champagne or silver in color and set with diamonds and blue sapphires) also available on the secondary market. Depending on the year produced, the ref. 16613 also features either a holes or no holes case and either Tritium or LumiNova used for the luminescence on the dial and hands.Regardless of the year of production, all two-tone Rolex 16613 Submariner watches are powered by Rolex’s trusty Caliber 3135 automatic movement. The 31-jewel movement beats at a rate of 28,800bph and includes a date complication, a 48-hour power reserve, automatic winding technology, and a sophisticated Breguet overcoil balance-spring. The movement has been a fixture in many Rolex wristwatches for more than three decades, and for a good reason. The Cal. 3135 has proven itself to be an accurate and robust movement, which can deliver decades of reliable performance if properly maintained.
If you have a vintage Rolex Datejust manufactured prior to the introduction of Caliber 3035, then your particular model is a non-quickset Datejust. To set the date and time on a Non-Quickset Rolex Datejust, follow these steps:Unscrew the winding crown by turning it counterclockwise until it releases from the case.Turn the crown clockwise around 25 times to manually wind the watch (it’s always a good idea to hand-wind the watch while setting it even if it is an automatic movement).Pull the crown out to the last notch.Rotate the crown to advance the timekeeping hands. Keep turning until the correct date appears in the date window. When the correct date appears, you are now in AM hours; now set the time accordingly taking into consideration if it is currently AM or PM.Push the crown all the way back in and screw it down to the case.To set the date and time on a Quickset Rolex Datejust, follow these steps:Unscrew the winding crown by turning it counterclockwise until it releases from the case Turn the crown clockwise around 25 times to manually wind the watch (it’s always a good idea to hand-wind the watch while setting it even if it is an automatic)Pull the crown out one notch to set the date (the timekeeping hands will continue to run in this position).Rotate the crown to adjust the date.
