The Rolex Oysterquartz was a quartz watch made by Rolex.
Unusually, its movement features a mechanical lever escapement driven by a simple permanent magnet moving coil motor mechanically similar to a d'Arsonval galvanometer.
At the end of the 1970s, the Swiss watch industry was affected by the quartz crisis. Japanese watchmakers supplied the world market with large quantities of quartz watches. [1] Rolex duly put forward a new line of watches, producing the Datejust Oysterquartz. It faced the Asian markets seeking to keep alive interest in Swiss watchmaking, an industry that seemed dominated by the Japanese quartz watch.
The Datejust Oysterquartz dates back to 1976. [2] The design differs greatly from the classic Rolex line and carved characteristics of the period: a completely angular case, an integrated band with a polished finish and sapphire glass. The whole range consisted of three versions: gold, steel with white gold bezel, and steel and yellow gold. The Datejust Oysterquartz was initially overlooked in Europe; however, it was much sought-after on the Asian and American markets. There was renewed interest in the watch once Rolex decided to take the Oysterquartz out of production. The era of the Rolex quartz watch ended in 2001, after less than 30 years. The Rolex Datejust Oysterquartz began to appear in auction catalogues, becoming a valued collectors’ object.
Model numbers of the Rolex Oysterquartz include:
Rolex SA is a Swiss watch designer and manufacturer based in Geneva, Switzerland. Founded in 1905 as Wilsdorf and Davis by Hans Wilsdorf and Alfred Davis in London, the company registered Rolex as the brand name of its watches in 1908 and became Rolex Watch Co. Ltd. in 1915. After World War I, the company moved its base of operations to Geneva because of the unfavorable economy in the United Kingdom. In 1920, Hans Wilsdorf registered Montres Rolex SA in Geneva as the new company name ; it later became Rolex SA. Since 1960, the company has been owned by the Hans Wilsdorf Foundation, a private family trust.
The Rolex Cosmograph Daytona is a mechanical chronograph wristwatch designed to meet the needs of racing drivers by measuring elapsed time and calculating average speed. Its name refers to Daytona, Florida, where racing flourished in the early 20th century. It has been manufactured by Rolex since 1963 in four distinct generations ; the second series was introduced in 1988, the third in 2000 and the fourth in 2023. While cosmetically similar, the second series introduced a self-winding movement, and the third series brought manufacture of the movement in-house to Rolex.
The Rolex Oyster Perpetual Date GMT Master is part of the Rolex Professional Watch Collection. Designed in collaboration with the now defunct Pan American Airways of the United States for use by their pilots and navigators, it was launched in 1954.
The Rolex Oyster Perpetual Submariner is a line of sports watches designed for diving and manufactured by Rolex, resistant to water and corrosion. The first Submariner was introduced to the public in 1954 at the Basel Watch Fair. It was the first watch to be waterproof up to 100 metres (330 ft). The Rolex Submariner is considered "a classic among wristwatches", manufactured by one of the most widely recognized luxury brands in the world. Due to its huge popularity, there are many homage watches by well-established watchmakers, as well as illegal counterfeits. The Rolex Submariner is part of Rolex's Professional line.
A diving watch, also commonly referred to as a diver's or dive watch, is a watch designed for underwater diving that features, as a minimum, a water resistance greater than 1.1 MPa (11 atm), the equivalent of 100 m (330 ft). The typical diver's watch will have a water resistance of around 200 to 300 m, though modern technology allows the creation of diving watches that can go much deeper. A true contemporary diver's watch is in accordance with the ISO 6425 standard, which defines test standards and features for watches suitable for diving with underwater breathing apparatus in depths of 100 m (330 ft) or more. Watches conforming to ISO 6425 are marked with the word DIVER'S to distinguish ISO 6425 conformant diving watches from watches that might not be suitable for actual scuba diving.
The Rolex Oyster Perpetual Datejust is a self-winding chronometer manufactured by Rolex. Launched in 1945, the Datejust was the first self-winding chronometer wristwatch to indicate the date in a window on the dial. Today, it is available in a variety of sizes from 28mm to 41mm, in stainless steel, two-tone gold, and solid gold versions.
The Rolex Oyster Perpetual Date Sea-Dweller is a line of diver's watches manufactured by Rolex, with an underwater diving depth rating of 1,220 meters and up to 3,900 metres (12,800 ft) for the Sea-Dweller Deepsea variant.

The Rolex Sea-Dweller is part of Rolex's Professional line.
The J12 is a line of Swiss made luxury watches introduced in 1999 by French haute couture house Chanel. The J12 was launched in 1999 and is considered as a unisex watch. The watch was designed by the artistic director of the house, Jacques Hélleu, who found inspiration in the two worlds he loved most: automobiles and sailing. Chanel uses highly scratch-resistant ceramic for the watch's case and bracelet. Other materials are used as well, such as titanium and for one of the house's limited edition watches, sapphires were used to create the entirety of the bracelet and case.
The Rolex Yacht-Master is a luxury sports watch manufactured by Rolex and first introduced in 1992 as Reference 16628 in 18-karat yellow gold. In 1994, Rolex released a lady's model (69628) and a mid-size model (68628) at 35mm, marking the first time in Rolex history that a professional series watch was available in smaller than the standard size case. In 1996, Rolex introduced two-tone to the lady's and mid-size line.
The Rolex Oyster Perpetual Milgauss is a wristwatch model introduced by Rolex in 1956 with model number 6541. The Milgauss was advertised as “designed to meet the demands of the scientific community working around electromagnetic fields”. The first of its kind, it is capable of withstanding magnetic fields of up to 1,000 gauss and became known for being worn by scientists at the European Organization for Nuclear Research (CERN) in Geneva. Its resistance to magnetic interference stems from a shield inside the case made of ferromagnetic alloys, which protects the movement. This shield consists of two components, one screwed to the movement and the other to the case. In addition, its Caliber 3131 movement includes paramagnetic materials.
The Omega Seamaster 200 Omegamatic is a midsize automatic quartz watch that Omega produced from 1997 until 2000.

The Rolex Oyster Perpetual Day-Date is a COSC certified, self-winding chronometer manufactured by Rolex. Initially presented in 1956, the Day-Date was the first watch to display the date as well as the day, spelled in full. The calendar display is offered in 26 languages.
The Omega Seamaster is a line of automatic winding mechanical diving watches from Omega with a history that can be traced back to the original water-resistant dress watch released in 1948. The Seamaster collection is perhaps best known today for the Seamaster Diver Professional 300m model that has been worn in the James Bond movie franchise since 1995. Originally conceived as a dressy, water-resistant timepiece, the Omega Seamaster has evolved to a robust sports watch line, typically with a stainless steel case, robust water resistance, and an official chronometer-certified movement within. The Diver Professional 300m is most famous for its "train track" five link steel bracelet, its helium release valve at the 10:00 position, the wave pattern dial on certain model generations, and the skeletonized handset.
The Rolex Yacht-Master II is a sport watch made by Rolex, unveiled in 2007 and first introduced in March 2010 with the models 116688 and 116689.

At Baselworld 2013, the watch was available for the first time in 904L steel, the model 116680, fitted with a Cerachrom bezel insert in blue ceramic. Originally, the Yacht-Master II used Rolex's 4160 movement but with the introduction of the model 116680 in 2013, the movement was updated to the 4161 movement specifically designed for the Yacht-Master II. All Yacht-Master II watches have a case size of 44mm.
The Omega Marine Chronometer was the first quartz wristwatch ever to be awarded certified status as a marine chronometer.
