Almost all modern Rolex watches will be named after the “oyster forever replica watch”, but the Rolex portfolio actually consists of two main lines: the professional and the classic. The watch has a waterproof oyster shell, which is different from the Cellini line of pure skirt watches. Professional collections may contain the most easily recognizable names, tool models such as submarines, Daytona, and GMT-master. Each was (and still is) designed to do a specific job, whether it was recording dive times, detour times, or time in other countries. 
The classic series also has some heavyweights, such as day-date, the ultimate expression of prestige and achievement, and date-just, an iconic all-rounder who is often seen as a bridge between the two groups. In general, the classic watch is the simplest, both aesthetically and in terms of complexity. The sky dweller’s wonderful almanac and Greenwich mean time features can’t stand the rest of the range being relatively conservative in style and quite modest in features. One of the most humble, low-key is the Rolex Oyster Perpetual watch.
Every watch made by fake Rolex (again ignoring the Cellini line) is technically an oyster forever. The brand name comes from oyster shells, which are at least 100 meters waterproof. The brand developed an automatic winding sport in the 1930s and named it Perpetual. So what we usually call a “Marine” is actually officially known as the Rolex oyster permanent Marine.
However, there has always been a separate collection of watches, where everything irrelevant has been stripped down to three hands telling the time, and nothing as unusual as a display of dates. This is the official Rolex oyster forever line, the brand’s cheapest and arguably the most versatile product.
Like its close cousin Datejust, the modern oyster forever collection is designed to appeal to as many people and as many flavors as possible. It comes in five sizes, starting at 26mm, making it the smallest watch ever made by Rolex. In addition, 31mm, 34mm, 36mm and a relatively new version (2015) are available in 39mm sizes.
Tracing its long history, you’ll find a handful of precious metal versions of 9k, 14k, and 18k gold, in yellow and pink. It was also one of the first to be released as a Rolex. Rolex is the brand’s own combination of gold and steel. Today, these cheap replica watches are made of forged stainless steel, underscoring Oyster Perpetual’s longstanding position as the first choice for entry-level watches.
