The first Accutron was manufactured in 1960 and was the watch chosen by some of the'Original Seven' NASA astronauts to accompany man on his first journeys into space. Scott Carpenter famously modeled a Bulova Accutron'Astronaut' on the front cover of Paris Match in 1962.Contrary to popular myth the Accutron only flew in space a couple of times on the wrist of an astronaut. It was not the watch chosen by NASA as the astronaut flight qualified time piece, this accolade goes to the Omega Speedmaster Professional. The Omega however was never (except in Apollo 13) used as the primary reference for any mission critical activities. Accutron movements were used in panel clocks and as instrument timers. Even today there is still an accutron tuning for keeping time on the moon. Yes that's correct, the watch uses a tuning fork as its prime moving element. It is a well understood physical principle that the faster your initial reference the more accurate your time keeping will be. The most accurate clocks nowadays use the vibrations of a caesium atom as their reference. In the 1950s the best mechanical watches could rely on a prime moving element with a frequency of around 2 Hz (That is two'beats' per second). Max Hetzel an engineer employed by the Bulova Watch Company of Bienne Switzerland designed an electrically excited tuning fork movement with a a frequency of 360 Hz. Bulova claimed an accuracy of 2sec per day or 1 min per month. This was the only movement capable of the accuracy demanded by spaceflight. Accutrons were used as time references in many satellites and also to control some of the Apollo moon experiments. The Tuning Fork Movement is absolutely unique in operation emitting a distinctive hum and featuring a sweep seconds hand. Here's a reproduction of an advertisement produced by Bulova in the early 1960s. The Accutron was SO accurate that the US Government once asked Bulova to delay the release of the revolutionary movement for fear the technology may fall into the hands of the Russians. The reason for this was the US would be launching new satellites timed by the Accutron and they simply did not want the Russians to benefit from the same precision. After the Explorer 6 was launched into orbit, Bulova was given the go-ahead to release the commercial timepieces featuring the Accutron movement.
Nothing says 70s style like a Jumbo C-Cased Compressors! This Bulova is a huge 41mm in diameter excluding crowns, 44.5mm lug to lug and 20mm lug spacing, those "cut in" solid lugs giving any strap an incorporated look.
Ten years into the life of the original Bulova Accutron came the Deap Sea diver you see here. This is really a great looking and exotic instance of a Bulova.
The case is a compressor with inner rotating bezel (thus the dual crowns, both of which are original and signed). Screw-down case back marked N0 precisely dating the watches manufacture to 1970.
Every discerning collector should have at least one tuning fork caliber, hell at least one diver tool watch, at least one compressor... This watch pretty much covers the lot =. A Really Classy, Two Tone Dial Black Grey with bright steel tritium indexes and white stick tritium hands, white centre sweep seconds, and being a tuning fork, what a sweep it is!Original Day Date rings at 3. Rarer Variation Yellow Outer ring. Inner Rotating bezel is a classic count up divers bezel. And the whole thing looks cool as hell under a UV light =. An excellently suited black heavy leather perforated watch strap somewhat synonymous with the vintage tool watch style. We have mentioned the RISE of the accutron caliber and the spaceview watch BUT the demise! Oh the demise of the accutron caliber is much more poignant, the watch is a "TRANSITIONAL" Caliber not cheap chinese mass produced "quartz" they evolved into but an intermediate age of technology quickly surpassed by cheaper quicker more efficient quartz and otherwise electrical watches BUT this ADDS to the value of these watches rare enough due to their Intermediate technological design and EVERY DAY these watches become rarer. SO to find one in ALL ORIGINAL SERVICED AND RUNNING condition like this is a sure investment.. Day: set by changing 18-24h. Specs as always curtesy of Dr Ranfft. Interestingly, as is so in vogue at present, the watch has had a recent, revitalisation in the form of a pretty decent re-issue / homage from the modern Bulova Watch Company.
Well we all know what a decent re-issue can do to a vintage models desirability.. We can offer a comprehensive servicing facility we can service most watches at a fraction of the high street cost, we can look after most watches from pocket watches to trench watches to high end chronographs.
