![]() because no original hands were applied, or because a model was converted which never was available as Spaceview. The Spaceview models are highly collectible, and therefore many watches with dial are converted to Spaceviews. Lots of informations about this kind of watch is presented in Accutron Watch Page Just driving the fork is done electronically. From the high frequency tuning fork, replacing the slow balance, down to the train pure mechanical action. Tuning-fork watches are the highest degree of mechanical watch evolution. ![]() Movement: M9, Bulova, Brevet-Patent, Swiss Made - E - calibre Bulova 2141, gold plated, 15 jewels, 2 visible gold settings, electronically controlled tuning fork, 360Hz Spaceview 2020: Black leather strap with double-press deployant closure.Bidfun-db Archive: Wrist Watches: 709: Gents Bulova Accutron Spaceview, Tuning Fork, 1969ħ09: Gents Bulova Accutron Spaceview, Tuning Fork, 1969Ĭase: 1-767786, M9, Bulova, Patented, Stainless Steel - 770, CB, Swiss - steel, plastic crystal, fold-out setting knob, separate battery screw cap, back screwed with ing nut, 38x42mmīand: original, steel, buckle with spring extension, 190mm esxtending to 194mm.Stainless steel case and bezel with stamped Accutron logo and turbine design on the case back.Blue open-work dial and silver-tone hands DNA: Silver-grey accent on the outer hour/minute ring.White hour and minute hands and orange second hand.

Tech Specs from Accutron We’ve linked to the individual collections up above, but you can also just head on over to and get your fix that way as well. Accutron announced itself to the world the other week with their new podcast ( covered here), and now they’ve made a giant electrostatic splash with these new watches. The case is a bit larger (see the specs below), but pricing has dropped a bit, coming down to $3,300 for the four versions in this collection. While the dial itself is still open-worked, the way they’ve used color here actually softens the impact a bit – in my book – and does freshen up the design. If, on the other hand, you’d prefer to see that design updated and reimagined a bit more, that’s where the Accutron DNA comes to bear. For this, you’ve got two versions – the standard (with a grey chapter ring) coming in at $3,450 and the 300-piece limited edition ( $4,000) with a green chapter ring. While the original was showing off the tuning fork, here, we’ve got that electrostatic movement taking pride of place. Just the 1960s version, the Accutron Spaceview 2020 has a bright green dial, plenty openworked to show off the movement held in. The first watch that the new movement is housed in is the Accutron Spaceview 2020. These two motors are synchronized, and are intended to provide accuracy at +/- 5 seconds per month. That energy then goes out to twin motors – one that powers the sweeping seconds hand, and another that powers the step motor driving the hour and minute hands. Rather than winding a mainspring, though, those rotors spin past electrodes, generating energy that’s stored in an accumulator. By that, I mean that it’s got two rotors that spin as a result of your movement. However, it does borrow a trick from your favorite automatic watch. Is the movement a mechanical? Well, no, not really. What IS a surprise is the movement that’s taking up home in the Bulova Spaceview 2020 and DNA. It shouldn’t be any surprise that the re-launched Accutron brand would go back to that design for inspiration. For Accutron (or Bulova, if that’s how your memory works that said, the brands are distinct now) the Spaceview of the 1960s was a revelation.
