You can check the time on your phone, but a mechanical watch gives you something more interesting to look at. The Bulova Classic Sutton Automatic 96A135 puts part of its movement on display through an open-heart dial, pairing visible mechanical components with a black leather strap and silver-tone stainless steel case. It’s a traditional dress watch with enough detail to stand apart from a basic analog model.

Listed at $311.15, this watch features a Japanese automatic movement, a 42mm case, a 24-hour indicator, and an exhibition caseback. It’s a compelling option if you want a mechanical watch that shows some of its inner workings while keeping a classic appearance.
An Open-Heart Dial With Mechanical Detail
An open-heart design gives you a view of the movement through an opening in the dial. Bulova calls this its heartbeat feature, and it adds visual interest to an otherwise traditional watch face.
Black provides the backdrop for silver-tone accents and Roman numeral styling. A small-seconds display tracks the passing seconds, while a separate 24-hour indicator shows the hour on a 24-hour scale. Luminous hands also help you read the time when lighting is limited.

You get the appeal of visible mechanical components without a fully skeletonized dial. The remaining dial surface keeps the layout recognizable, and the black-and-silver combination works with office clothing, dress shirts, and formal outfits.
If you enjoy mechanical watches but find exposed skeleton dials too busy, this design offers a good middle ground. Anyone who prefers a clean three-hand layout should choose something simpler.
A Self-Winding Movement With an Exhibition Caseback
You don’t need a battery to keep this watch running. Its Japanese automatic movement uses a rotor to wind the mainspring as your wrist moves, storing the energy needed to operate the mechanism.
Regular wear helps keep it wound, but leaving it unused long enough will eventually exhaust its stored energy. When that happens, you’ll need to get it running and set the time again. That’s a normal part of owning a mechanical automatic.

An exhibition caseback lets you see the movement from behind, complementing the smaller opening on the dial. Both features make the mechanism part of the watch’s design, giving you something to appreciate beyond the time display.
Choose this one if you enjoy traditional watchmaking and don’t mind occasional adjustments. If you want a watch that continues running for long periods while stored, quartz is the more convenient choice.
A 42mm Stainless Steel Case and Black Leather Strap
At 42mm wide, the stainless steel case gives this watch a noticeable presence on the wrist. Its round shape, silver-tone finish, and black dial follow familiar dress-watch styling, while the exposed movement adds a distinctive detail.
If you normally wear smaller watches, the case diameter deserves attention. Overall fit also depends on the case’s proportions and your wrist size, so diameter alone doesn’t determine how comfortably it will wear.

Bulova uses a metalized domed mineral crystal over the dial. The curved surface complements the traditional appearance, although mineral crystal can scratch when it contacts harder materials.
A black leather strap completes the design, secured with a push-button deployant clasp. The clasp opens using its release buttons, providing an alternative to the traditional pin-buckle arrangement found on many leather watch straps.
This combination makes sense if you want a larger dress watch with a leather strap. If compact cases or metal bracelets are your preference, another model will be a better choice.
Everyday Features and Water Resistance
Bulova rates this model for 30 meters of water resistance, covering incidental exposure such as splashes and rain. It isn’t intended for swimming or showering, and the leather strap is another reason to avoid prolonged contact with water.
Luminous hands help with visibility in dim conditions, while the small-seconds display and 24-hour indicator add useful information to the dial. These features complement the automatic movement without changing the watch’s traditional character.

You also get a three-year limited warranty, with coverage subject to the manufacturer’s terms. It’s a useful inclusion for a mechanical timepiece, particularly if you’re buying your first automatic.
For office wear, dinners, and everyday use away from water, this configuration is a practical choice. If your routine involves swimming, outdoor sports, or frequent water exposure, buy a watch designed for those conditions instead.
Is the Bulova Sutton Automatic Worth Buying?
Visible mechanical components are the strongest reason to choose this watch. The open-heart dial and exhibition caseback let you appreciate the movement from both sides, while the black dial, stainless steel case, and leather strap maintain a traditional appearance.
Its 42mm case gives it a noticeable presence, and the additional time displays bring more detail to the dial. You’ll need to accept occasional resetting and limited water resistance, but those are straightforward trade-offs for this type of watch.
