Frequently Asked Questions about Bulova Automatic
What movement is inside Bulova automatic watches, and who makes it?
Bulova automatics are powered by Miyota movements — the Japanese mechanical calibres made by Miyota, which, like Bulova, is owned by the Citizen Group. That shared ownership matters: it means Bulova draws on one of the world's largest and most proven movement makers rather than an anonymous third party. Miyota's automatic calibres (the 8 and 9 series) are among the most widely used self-winding movements in the industry, trusted for reliability and easy serviceability worldwide.
What does "21 jewels" mean on a Bulova automatic — and is it a good thing?
The jewels are synthetic rubies set at the movement's key friction points to reduce wear and keep timekeeping stable over decades. Twenty-one jewels is the hallmark of a properly built mechanical automatic — it's the configuration of the Miyota 8-series movement, not a marketing number. It signals a genuine self-winding mechanical watch engineered to last, which is a large part of why this collection offers the finishing and feel of far more expensive pieces at an accessible price.
Are Bulova automatic watches good quality and good value?
Yes — this collection is arguably Bulova's strongest value proposition. Because the movements come from sister-company Miyota, Bulova delivers a reliable Japanese mechanical engine in a well-finished case for a fraction of what a comparable Swiss automatic costs. Expect accuracy within the normal range for mechanical watches (a small number of seconds per day, which self-corrects as you wear it) and the tangible appeal of a sweeping seconds hand and a movement that runs on your motion alone — no battery, ever.
How long does a Bulova automatic run, and how do I wind and set it?
A fully wound Bulova automatic holds roughly 40 hours of power reserve, so worn daily it never stops. If it's been sitting unworn for a couple of days, wind the crown 20–30 turns (or simply give it a gentle shake) to restart it, then set the time. You can't over-wind it — the movement has a built-in clutch that prevents damage once fully wound, so it's genuinely low-maintenance for a mechanical watch.
Which Bulova watches are automatic rather than quartz, and where are they made?
Not every Bulova is automatic — much of the wider range is quartz — so the Automatic collection is the line to choose if you specifically want a self-winding mechanical movement (look for "Automatic" and the 21-jewel designation). These are American-heritage designs from a brand founded in 1875, now part of the Citizen Group, fitted with Japanese Miyota movements and assembled to Citizen Group standards. Every automatic sold by Starbuy is brand-new, authorised stock with full manufacturer's warranty.
