Common Rolex Terminology and Definitions:
Need to catch up on all of the Rolex Terminology and Definitions? Here’s a guide made just for you:
904L Stainless Steel: The type of stainless steel Rolex uses in making its watches. In 1985, Rolex was the first watchmaking brand to use 904L steel because it’s a highly corrosion-resistant alloy that acquires an exceptional sheen when polished.
Acrylic crystal: previous generation material used on Rolex crystals comprised of acrylic, a plastic like material. The advantage is that it can be polished.

Arrowhead: hand and hour markers found on vintage pieces that are shaped in the form of arrow heads
Automatic: Automatic watches are wound by the movement of the wearer. This movement causes a weight inside the watch to rotate backwards and forwards. The weight is connected by a gear train to the barrel arbor, which is hooked to the mainspring, thus winding it and keeping it in constant tension.
Bark Finish: finish found on presidential bracelets where the center links are etched to look like tree bark.
Baton: hands that look like long rectangles with no points and can be luminous or not
Bevel: the angled corner on some older style professional mode cases, often obliterated by multiple polishes, desirable on collectors market.

GMT: The Rolex GMT-Master wristwatch was originally designed in collaboration with Pan American Airways and issued by the airline to their crews on long-haul flights. (“GMT” in the name stands for Greenwich Mean Time also known as Coordinated Universal Time).
Gold through clasp: the gold stripe from the band is continued into the buckle, this feature was introduced as early as 1999 in the 16613.

Rolex Terminology and Definitions
Quartz: Quartz watches use a tiny energy cell (or battery) to replace the mainspring as the power source. The oscillating mass is replaced by a tiny piece of shaped quartz crystal, which is tuned to a frequency of 32,768 Hz (cycles per second)—this is often called the piezoelectric effect and is similar to that of a tuning fork. A system of integrated circuits then divides the frequency into one-second pulses to drive a tiny rotor, which drives the hands.
