Description

It could be argued that Rolex launched the Day-Date much too early in 1956; how do I know this – well look at the facts, the original model the 6511 was replaced after less than a year by the new 6611 which looked identical but had an upgraded free sprung version of the 1055 movement. In turn, less than a year later this was superseded by the 6611B, which solved a problem which had bedevilled both earlier versions; the accuracy fell off around midnight as the watch struggled to flip over the heavy day disc as well as the much lighter date wheel. 

 The 6611B solved this by fitting table jewels atop the movement to reduce the friction and reprofiling the Day cam, so that energy was gradually gathered over a 24 hour period, rather than in a short period before midnight

The Day-Date is an early 6611B from 1957, and benefits from these mechanical improvements whilst still retaining the  ‘pie-pan’ dial and leaf hands of the earliest versions.

The movement is the modified 25 jewel calibre 1055B, which can be recognized by the capital letter B stamped next to the calibre number, and also by the fact that it is 0.1mm taller than the earlier versions. The balance cock has instructions to the watchmaker on how to adjust the timing, as most would never have seen a free sprung balance previously. It is fitted with the Para choc shock protection, which was a predecessor to the Kif now used.

The dial is the classic ‘Pie Pan’ version with applied double diamond cut batons for the 6 and 9 positions and single ones for the remaining hour indices; the faceted leaf hands do not have (and never have had) luminous inserts, as this was very much a dress watch.

The case is the much loved tonneau shape with finely milled bezel and a combination of brushed and polished finishes, both the screw crown and the screw back have had new gaskets fitted during the recent service and it easily passed the 50m test.

The case is 95%, whilst the movement and the dial are both 90%

The watch measures 34mm Diam, 44mm lug to lug and is 12.5mm high; it takes a 20mm strap and an original brown Rolex alligator strap with original gold plated buckle is fitted to the watch.
