A piece from the Bulova Classic Collection that exudes a mature presence.98A319Introducing. The main feature of this model, released in May 2025, is the "skeleton dial" that shows the movement of the movement on the entire surface of the dial. It uses a tonneau (barrel-shaped) case, and the bridge part is decorated with a sunray finish, giving the movement parts a beautiful finish.

The case has a bi-color finish of navy PVD processing and stainless steel, and the deep navy color creates a sense of cleanliness and class at the same time. The gently curved curved sapphire glass creates a sense of unity with the case, and the hairline-finished case sides tighten the whole thing. If you're looking for a skeleton watch, you won't find many models that are as conscious about their "presentation" as this one.

■ “How to show off Bulova”: skeleton x tonneau case

98A319 is a model that condenses Bulova's idea of ``showing the movement itself as a design.'' The slightly unique case shape called tonneau (barrel shape) forms the outline of the skeleton dial, giving the face a three-dimensional feel that makes you feel as if you are looking at a cut section of a luxury watch. Different from round cases of the same size, the tonneau has a dramatic impression on your wrist.

By applying sunray (radial hairline) decoration to the bridge part, the design concept of functional parts becoming decoration is thoroughly implemented. Watch enthusiasts will enjoy watching the movements of the movement, and those experiencing a skeleton for the first time will be amazed at how interesting a watch that allows you to see its contents can be.

■ “Completed exterior” of navy PVD x curved sapphire

The navy PVD treatment applied to the case has an intellectual sex appeal that is different from regular silver or black. It doesn't overstate its strong presence, yet it's definitely there -- it has a casual, adult feel. The curved sapphire glass and case curve gently in the same direction, creating an organic appearance whose outline changes depending on the viewing angle.

The glass with anti-reflection coating allows you to clearly see the details inside the skeleton even in bright outdoor conditions, and the hairline-finished case sides give the bold skeleton face just the right amount of attention. The attention to detail on the exterior is typical of Bulova quality.

■ ``Reliable practical design'' with automatic winding and 42-hour power reserve

Skeleton watches tend to have the image of being aesthetically focused and difficult to maintain, but the 98A319's automatic movement has a 42-hour power reserve, so if you wear it every day, it will continue to run without any problems without winding. The bridge design, which pays particular attention to the finish of the movement parts, can also be enjoyed through the see-through back.

It is water resistant to 5 ATM, so you can wear it with confidence even in everyday situations around water. Weighing approximately 186g, the metal bracelet has a rich texture that makes it stand out when worn on your wrist.

■ Buyer's comment

When I first saw 98A319, I was honestly surprised at how rare the combination of "navy PVD tonneau case x skeleton" was. While black and silver are the norm for skeleton watches, the decision to choose navy is simply excellent, and it has an intellectual and sexy appeal. The sunray finish on the bridge and the attention to detail in the curved sapphire glass are genuine, and I feel that this is Bulova's true strength. This is a book that I would confidently recommend to both skeleton lovers and those who want to try skeletons for the first time.
