Rolex Oyster Perpetual Air-King-Date Ref.5700 dated 1969
This update opens with a smart version of the Air-King-Date Ref.5700, a model that was introduced by Rolex in the 1960s. Similar in design to the Ref.5500 Air-King, the 5700 features a date aperture and a slightly larger case with a diameter of 35mm. This example of the model has an unusual, light grey, ‘linen’ finished silvered dial. The watch is fitted with its original sprung riveted link Rolex Oyster bracelet. As part of the watch’s full service, it has been pressured tested for water resistance for depths up to 100 metres.
Breitling Top Time Ref.2211 c.1969
A bright and colourful chronograph, this model has a cushion-form case with a satin finish to the upper body. The silvered dial has unusually shaped elliptical subsidiary dials for constant seconds and a 45-minute chronograph register. At the edge of the dial, scales are calibrated for pulsometer and units-per-hour. The pulsation scale is graduated for 15 pulsations, meaning that the user may start their chronograph as they feel a subject’s first pulse and stop it after the 15th pulse, the chronograph seconds hand will then show the patient’s pulse rate on the orange scale to the edge of the dial. The UPH (units-per-hour) scale can be used to calculate hourly production rates or it may be used in the same manner as a tachymeter to measure speed over a set distance.
Rolex Cellini Ref.4121 sold in 1992
From Rolex’s Cellini range, this unusually shaped lady’s hexagonal wristwatch is in very good original condition, retaining all of its original accessories. The silvered dial has applied gold baton indexes which, together with the hands, have blackened surfaces to increase legibility.
The Cellini is complete with its original Rolex certificate, swing tags, booklets, red leather Rolex card holder and inner and outer presentation cases.
Omega Genève Ref.136.015 c.1969
Ref. 136.015 is a very unusual model that was first introduced by Omega in 1967. This reference has a distinctive matt white dial with printed orange markers at each five-minute/five-second increment together with a matching orange centre seconds hand. The steel case has unusual long lugs and there are pronounced crown guards, a feature seldom seen on vintage Omega models. Manually wound the watch is powered by Omega’s calibre 613 which has provision for semi-quick date change.
Omega Seamaster Ref.166.002 c.1966
A classic Seamaster model, this reference was first introduced by Omega in 1962 and the present example dates to c.1966. The watch has a silvered dial with a light vertical satin finish and the applied hour indexes are centrally faceted. Automatically wound via Omega’s calibre 562, there is also provision for semi-quick date change – although the date will change each day at midnight, it may be manually advanced when required by moving the hands backwards and forwards between 9pm and 1am.
Chris Clarke Handmade Horween Cordovan Straps
New to our range of Christopher Clarke for Black Bough watch accessories are these superb handmade chocolate brown straps which are made using the finest vegetable tanned Shell Cordovan from Horween in the U.S.A. The sides of the strap, buckle and fixed ‘keep’ are all hand sewn using linen thread coated with beeswax. The Cordovan has a light yet rich hand polished sheen. A contrasting lining of kangaroo leather is used; kangaroo is very strong, due partly to the fibres being nearly parallel to the surface and partly caused by the harsh conditions the animals are exposed to, the skin being very low in fat which causes few voids during the tanning process, making the leather dense. These straps are available in the lug gauges of: 16, 17, 18, 19 and 20mm.
