Affordable Replica Rolex Datejust Watches For Sale Online

The first Milgauss was released in the mid 1950s. This was a new and interesting time for Rolex as they were experimenting with a range of new-era sports and professional Rolex Datejust Replica Watches. These tool watches featured robust steel Oyster cases with rotating bezels and were the forefathers of the current sports watches. Rolex experimented with the Mono Meter and Turn-O-Graph names, keeping the latter. The Sub Aqua moniker was ultimately changed to Submariner and then there was another black, rotating bezel watch called the Milgauss. Where the GMT-Master was referred to as the Aviators Watch, the Milgauss was referred to as the Scientists Watch. Aimed at those working in conditions of high electromagnetic fields, the watch was impervious to magnetic forces of up to 1,000 gauss.

Rolex always has, even up until current times, worked with the highest caliber partners in their research and development. The Tektite project for the early Sea-Dwellers, Pan-Am with the GMT-Master and Comex on the Deep Sea Sea-Dweller; all these relationships were key to the development and testing of professional model watches. The Geneva-based Conseil Europen pour la Recherche Nuclaire or CERN is the worlds pre-eminent particle physics research facility. In the mid to late 1950s, the Milgauss was put through its paces by scientists at CERN who confirmed that the watch could be exposed to magnetic fields of up to 1,000 gauss without any impediment to timekeeping.

The first Milgauss reference was the 6543 with a steel case measuring 38mm across and an unusual lug width of approximately 19.5mm. The rotating bezel was marked with either unique font Submariner-esque divisions of tens (10, 20, 30, etc.) or single units of one to five. The 6543 was equipped with a unique caliber reference 1080, which was modified from the base caliber 1030.

The dials had a beautiful honeycomb finish, that actually looks like a weave construction. You may be aware that Faraday cages are often of a mesh construction, therein, it is widely believed that the dials on the early Milgauss watches were made in such a way as to make the dials a key component of the Faraday cagetruly, not just a pretty face. These dials had applied arrow markers at 3, 6 and 9 and painted luminous dots between the quarter markers. The word MILGAUSS was printed in red and it is quite common now to see this lettering faded to a pleasing pink hue. The main anti-magnetic properties of the watch came from the use of a soft-iron shield around the movementa small Faraday cage. The steel case had an iron ring inserted around the movement alongside a thick caseback. The 6543 is something of a mystery to collectors and the examples known are very inconsistent, so stating cast-iron (pardon the pun!) facts is at best difficult and more likely impossible.

Due to the fact that this was a time of experimentation and prototyping, the references of the very first sports watches change quickly and in some cases co-exist. The second reference for the Milgauss was the 6541. Visually very similar to the 6543, the biggest addition cosmetically to the 6543 was the so-called lightning-bolt seconds hand. The 6541 debuted in 1957 and was again produced in very small quantities, estimated to be around 200 pieces in total. Rolex utilized the 1080 caliber still and the honeycomb dials remained. The case size was again 38mm, but the lug width increased to the sports watch standard of 20mm. Internally, there was a small change. The iron ring around the movement remained, but instead of a thick caseback as seen on some examples of its predecessor, the 6541 had an additional inner caseback as well as a standard steel outer caseback. The Faraday cage was therefore constructed by the inner ring and inner caseback.
