Bulova Classic Aerojet (98A187): An Open-Heart Automatic With a Familiar Movement Inside

An automatic open-heart dress watch with a genuine Miyota movement, the same maker behind Citizen’s Tsuyosa line. Specs, one seller caution, and the price.

Bulova Classic Aerojet (98A187): An Open-Heart Automatic With a Familiar Movement Inside

The Bulova Classic Aerojet (98A187) is a 41mm automatic dress watch with an open-heart grey dial and black leather strap, currently €264.51 on Amazon.ie.

This review is built from Bulova’s own official product page and multiple authorised dealer listings for this exact reference, including one genuine verified customer review found on Bulova’s own site. For the rest of Bulova’s range, including the Marine Star chronograph and the Lunar Pilot already reviewed here, see the full Bulova line-up on this site.

In this review
  • A genuine Miyota movement inside, not an in-house Bulova caliber
  • One real verified owner review, cited directly
  • A seller consideration worth knowing before buying
  • What 30m water resistance actually covers
  • Price €264.51 on Amazon.ie, sold through third-party marketplace seller LUX’S SONS S.R.L rather than Amazon directly.
  • The movement is genuinely Miyota, not in-house One independent retailer specifically identifies the automatic movement as a Miyota caliber, the same Japanese movement maker behind Citizen’s Tsuyosa line reviewed elsewhere on this site.
  • A real verified owner review exists Bulova’s own site carries a genuine customer review praising the fit and dial design, a small but real, checkable data point rather than an aggregate star rating alone.
  • Water resistance is modest 30m (3 ATM), consistent across every source checked, fine for light splashes only, not swimming or showering.
Same movement family as Citizen's Tsuyosa, different price bracket

Time Transformed, an independent watch review site, specifically identifies the automatic movement inside the Aerojet as a Japanese-made Miyota caliber, likely the 8215, viewable through the open-heart aperture and exhibition caseback. Miyota is the same Japanese movement manufacturer behind the standard Citizen Tsuyosa reviewed elsewhere on this site, though the two watches sit in different price brackets and use different specific calibers. It’s a useful data point regardless: the movement inside isn’t a mystery or an unbranded generic, it’s a known, widely used automatic mechanism with a long track record in watches at this price and above.

One genuine, verified customer review on Bulova’s own site praised the fit and the overall look of the colour scheme. It’s a single review, not a large sample, but it’s a real, checkable data point rather than an unverifiable aggregate number.

Bulova Classic Aerojet (98A187)
Miyota automatic movement Open-heart exhibition dial 40 hour power reserve

A genuinely well-specced automatic dress watch for the price, backed by a known, widely used Miyota movement rather than an unbranded mystery mechanism. The open-heart dial and exhibition caseback are real conversation-piece details, not just marketing language. Buying through a marketplace seller rather than Amazon or Bulova directly is worth a moment’s thought at this price, but it doesn’t undermine what’s a solid, honest watch.

Conclusion
  • Genuine Miyota automatic movement with visible mechanics, backed by one verified owner review
  • Modest 30m water resistance; confirm warranty terms directly given the discrepancy between this listing and Bulova's own site

The Aerojet earns real credit for using a known, widely used Miyota automatic movement rather than an unbranded mechanism, and the open-heart dial with exhibition caseback gives it genuine visual interest at this price. A verified customer review, though a single one, backs up the fit and design. The honest caveats are modest water resistance and a marketplace-seller purchase with a warranty discrepancy worth resolving directly before buying.
