Catalogue description
Dealer description — Bulang & Sons
In the end of the 1960s the famous Dial maker company “Singer” was asked by multiple swiss manufactures to design new dial proposals for their model lines. In their famous 1967/1968 catalogue they presented new design studies, print techniques, markers and finishes to multiple brands. In this catalogue some of the most famous Rolex dials started to see their light like the Yach-master Daytona and early versions of the exotic dials. But another interesting section was designed for the legendary Rolex Datejust. Many of these designs never saw production and were archived, but some found their way into production. Like this rather interesting and funky “Singer Block Markers” dial showcasing all the resemblance to one of the dial variations seen on the Datejust section in the Singer catalogue. We believe this is one of the design study dials which made the cut and was produced in small numbers. The marker shape clearly add a rather unusual but very interesting dynamic to the soleil silver dial. It definitely has a prototype feel and the vibe of the famous prototypes seen in the catalogue. The mirror filling in the markers gives so much detailing to the watch. In every angle the color changes from white to black, very funky. The combination of all these factors makes the watch stand-out. An out of the ordinary Datejust that steels the show ! The watch itself is in amazing sharp condition featuring a fat case, sharp fluted bezel and strong 6251h folded jubilee bracelet , with a clasp stamped 4 69. Furthermore this watch comes with an original Rolex watchbox , punched guarantee paper , the big chronometer certificate and a 2019 Rolex service paper and booklet , what could we more wish for ?!

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

Atlas type guide
Calendar, moon-phase and perpetual calendar watches
Calendar complications range from a simple date to the perpetual calendar, which automatically allows for months of different lengths and leap years until 2100. Pocket watches with perpetual calendars were made in the eighteenth and nineteenth centuries; Patek Philippe made the first perpetual calendar wristwatch in 1925, and series production followed in 1941. The annual calendar (Patek Philippe, 1996) needs correction only once a year.
Moon-phase displays use a disc with two moons and 59 teeth advanced daily, approximating the 29.5-day lunation; more precise trains reduce the error to one day in over a century.
What to look for
- Apertures or subsidiary dials for day, date, month and leap year.
- Moon disc under a 'bosom' shaped aperture.
- Recessed correctors on the case band for setting the calendar.
Dating clues
- Triple-date wristwatches: popular c. 1940–1955.
- Perpetual calendar wristwatches: from 1925 (unique) and 1941 (series).
