Service and Repair of the Bulova 23 Jewel Watch Service (Caliber 10 BOAC)
The servicing of this Bulova 23 Jewel watch, powered by the Caliber 10 BOAC movement, began with addressing the effects of many years of daily wear. The watch had not been serviced in a long time, and the constant contact with the wrist had left a noticeable buildup of grime around the case and lugs. Because the owner preferred to preserve the watch exactly as it was—requesting no cosmetic work, polishing, or crystal replacement—the focus was placed entirely on the internal mechanical restoration. The movement was fully disassembled, cleaned, inspected, and properly lubricated, bringing the watch back to reliable performance while maintaining the original character and appearance that held personal meaning for its owner.

Brief History of the Bulova 23 Jewel Watch (Caliber 10 BOAC)
The Bulova “23” line was introduced in the 1950s as one of the company’s flagship offerings, designed to showcase the brand’s advancements in durable, high-grade, mass-produced wristwatches. Featuring 23 jewels—more than many competing models of the era—the movement was engineered for improved shock resistance, reduced friction, and enhanced long-term reliability. The Caliber 10 BOAC represents one of the refined variants of the 23-jewel family, combining efficient automatic winding with the solid performance that helped make the “Bulova 23” both popular and long-lived. These watches were marketed as dependable everyday companions, bridging the gap between accessible pricing and high-quality mechanics. For more information visit The “Bulova 23” Series.
