Glashutte Replica Watches

Rolex spent the next five year developing its own quartz movement. They wanted to create a quartz movement that was superior to Beta 21 as well as the ability to use it in their Oyster case. Both the case and the movement were developed simultaneously, but the case was ready much earlier.

Rolex tested the case in the market with references 1530 (steel), and 1630 (2-tone) in 1974. The watches were equipped with mechanical automatic calibers 1570s and the new integrated case-and-bracelet design. These watches were made in very limited numbers.Glashutte Replica Watches It is estimated that there are only around 1500 total. They have become collector's items. The Oysterquartz was finally revealed in 1977.

The earliest Glashutte Replica Watches Mk1 17000, with a movement that hadn't been sent to COSC, was worn on the wrist.

Rolex wanted to incorporate a number improvements into its new quartz movement. The new modules were developed to be far more advanced than the Beta 21. The next-generation modules were over-engineered in many ways, with 11 jewels as well as the ability to "regulate" the movements during service.

Their finishing was stunning, perhaps even more than their mechanical movement. The movements could self-regulate based on ambient temperatures, making them extremely precise. These movements, which were manufactured in the first 18-months of production, weren't sent to COSC for chronometer tests. They are called Mk1. The dials of the Mk1 watches were relatively clean, with ROLEX DATEJUST at the top and OYSTERQUARTZ at the bottom.

After a change in the quartz crystal shape (it was now a tuning fork), the Mk2 movement was submitted to COSC to become chronometer certified. The change was made in 1978, and the Mk2 watches were then given the extra text on the dial.Patek Philippe Nautilus Replica Watches The upper half of the dial read Glashutte Replica Watches DateJUST, and the lower half featured the iconic Rolex text SUPERLATIVE CHIRONOMETER OFICIALLY CERTIFIED. The Mk1 is much more rare as it was only produced for 18 months out of the 25 years of Oysterquartz.
