The Maquina — Bulova's name for this model within the Classic line — makes no secret of its mechanics. The date window has been omitted deliberately, leaving the full width of the dial open to the skeletonised movement beneath. What you see through the sapphire is a Miyota 8N26, a 21-jewel automatic wound by the rotor or the wrist, running a 40-hour reserve. The case pairs rose gold-tone and gunmetal finishes across a 46mm diameter, which at 13.2mm thick sits flatter than most watches this wide. The silicone strap keeps the whole assembly to 109 grams — light enough that the size reads more visually than physically on the wrist. The exhibition caseback gives the same view from the reverse that the open dial gives from the front.

Learn more about Bulova
Joseph Bulova, a Bohemian immigrant, opened a jewellery shop on Maiden Lane in New York in 1875 and moved into watch manufacturing in the early twentieth century, building a plant in Sag Harbor and later a substantial operation in Queens.
Bulova's instinct for firsts was commercial as much as technical. It ran the first national advertisement for a watch brand in 1926, broadcast the first radio commercial in American history — a time announcement — in 1926, and aired the first television commercial ever broadcast in 1941, paying nine dollars for the slot.
The engineering came too. The Accutron of 1960 replaced the balance wheel with a tuning fork vibrating at 360 Hz, driven electronically. It was accurate to within a minute a month, far beyond mechanical watches, and it hummed rather than ticked. NASA used Accutron timing mechanisms in spacecraft, and one was left on the Moon in the equipment package of Apollo 11.
Bulova also made an enormous contribution to American war production, supplying military timing devices, and founded a school of watchmaking for disabled veterans.
The company was acquired by Citizen in 2008. Modern collections include the Precisionist, with a high-frequency quartz movement producing a smooth sweeping seconds hand, and reissues of the Accutron and the 1970s Computron.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 40 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
13mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as men's.
