Bulova Automatic Watch (Model: 98A187)

Items Description

The Bulova Automatic Watch (Model: 98A187) presents a captivating blend of mid-century aviation aesthetic and modern mechanical watchmaking. As part of the Aerojet collection, this timepiece is defined by its 41mm stainless steel case and a striking grey dial with an open-heart aperture, revealing the automatic movement’s 30-jewel heart-beat mechanism. It is a watch designed for those who appreciate visible mechanical artistry within a refined, everyday-wearable form.

 

The watch is paired with a supple black calf leather strap that complements the silver-tone case and grey dial, creating a versatile and sophisticated profile. Its boxed mineral glass crystal adds a vintage touch while protecting the dial, and the exhibition caseback offers a clear view of the self-winding rotor in motion. This model balances classic design cues with the satisfying function of an automatic movement, making it a compelling choice for watch enthusiasts and newcomers alike.

 

Key Advantages of the Bulova Automatic Watch (Model: 98A187)

 

1. Visible Automatic Movement with Heart-Beat Complication

The defining feature of this model is the open-aperture or "heart-beat" window cut into the dial at 12 o’clock. This aperture reveals the oscillating balance wheel in action, the core component that regulates the watch’s timekeeping. This visual element transforms the watch from a simple time-telling instrument into a kinetic piece of art.

 

• Open Aperture Design: A precise cutout on the grey dial offers a clear view of the balance wheel’s rhythmic oscillation.
• Self-Winding Movement: The automatic caliber is powered by the natural motion of the wearer’s wrist, eliminating the need for a battery.
• 40-Hour Power Reserve: Once fully wound, the movement stores enough energy to keep running for approximately 40 hours off the wrist.
• Exhibition Caseback: A clear crystal caseback on the reverse side provides a full view of the decorated movement, including the oscillating rotor.

 

2. Retro-Inspired Aerojet Design DNA

The watch draws its design language from the golden age of aviation, specifically the vector-jet era that inspired the Aerojet name. The 41mm stainless steel case features brushed and polished surfaces that catch the light, while the grey dial with applied indices and luminous hands ensures excellent legibility. The boxed mineral glass crystal adds a subtle dome that enhances the vintage aesthetic.

 

• Case Dimensions: A well-proportioned 41mm diameter and 20mm lug width ensure a balanced presence on the wrist.
• Dial Architecture: The grey, sunburst-brushed dial provides a rich backdrop for the silver-tone hands and hour markers.
• Luminous Elements: The hands are treated with luminous material for visibility in low-light conditions.
• Boxed Crystal: The domed mineral glass adds a classic, retro character to the overall profile.

 

3. Premium Black Calf Leather Strap

A watch is only as comfortable as its strap, and this Bulova model is fitted with a high-quality black calf leather strap. The leather is soft and flexible from the first wear, designed to break in quickly and conform to the wearer’s wrist over time. The material complements the silver-tone case perfectly, creating a cohesive and dress-forward look suitable for both business and casual settings.

 

• Material: Genuine calf leather for durability and a refined finish.
• Comfort: Padded construction ensures a comfortable fit during extended wear.
• Closure: A secure silver-tone buckle matches the case hardware for a unified appearance.
• Versatility: The black strap pairs easily with suits, dress shirts, or smart-casual attire.

 

4. Reliable Japanese Automatic Caliber

Powering the Aerojet is a reliable Japanese automatic movement, bearing 30 jewels for reduced friction and enhanced longevity. This movement is a workhorse in the watch industry, known for its accuracy and dependability. The self-winding mechanism uses a bi-directional rotor that winds the mainspring in both directions, making it highly efficient at converting wrist movement into stored energy.

 

• Jewel Count: 30 jewels provide smooth operation and minimize wear on moving parts.
• Winding Efficiency: The bi-directional rotor ensures quick winding with even minimal wrist movement.
• No Battery Required: The watch is powered entirely by motion; a simple daily wear routine keeps it running.
• Hacking Feature: The seconds hand stops when the crown is pulled out, allowing for precise time setting.

 

5. Everyday Water Resistance and Durability

With a water resistance rating of 30 meters (3 ATM), this watch is suitable for splash and rain resistance, making it practical for daily wear. The stainless steel case is both strong and corrosion-resistant, ensuring the watch maintains its appearance over time. The boxed mineral glass is scratch-resistant to a degree, providing adequate protection for the dial during regular use.

 

• Water Resistance: Rated to 30 meters, sufficient for hand washing and light rain.
• Case Durability: 316L stainless steel offers excellent strength and hypoallergenic properties.
• Crystal Protection: Boxed mineral glass provides a vintage look while resisting minor impacts.
• Everyday Practicality: The design combines vintage charm with modern durability for daily wear.

 

6. The Grey Dial: A Neutral Canvas for Mechanical Art

The grey dial of the 98A187 is more than a background—it is an active design element that enhances the watch’s character. Unlike stark white or black dials, the sunburst grey finish creates a subtle play of light, shifting from charcoal to silver depending on the viewing angle. This tonal quality makes the watch feel dynamic without being loud, allowing the open-heart aperture and silver-tone hands to stand out clearly. It is a color that bridges the gap between a classic dress watch and a modern tool watch.

 

• Sunburst Finish: The brushed texture catches light to create depth and luster.
• Neutral Versatility: Grey pairs effortlessly with any strap color or clothing shade.
• Legibility: The contrast between the grey dial and silver-tone hands ensures quick reading at a glance.
• Unique Identity: The grey dial sets this Aerojet apart from more common black or blue dial variations.

 

The Bulova Automatic Watch (Model: 98A187) successfully marries the visual excitement of an open-heart movement with the timeless appeal of a grey dial and stainless steel case. It is a watch that offers genuine mechanical interest without sacrificing everyday wearability. From the heart-beat aperture to the comfortable leather strap, every element is crafted to provide a satisfying ownership experience for those who value the intricacy of automatic watchmaking.
