The powerful drive of the tourbillon and the precise operation of the mechanism are a tribute to the sun, moon, and stars. The development of automatic winding movements has a history of over a century. Initially, automatic winding systems were merely a solution to the problem of frequent manual winding, lacking the rich functionality we see today. Early automatic mechanical movements used in watches had short power reserves and would stop running if not worn for a short period. Through continuous optimization and improvement, today's automatic winding systems can easily achieve power reserves exceeding 24 hours, even up to 100 hours.

   In daily wear, even alternating between two watches will not cause them to stop running due to lack of wear. This eliminates the need for frequent adjustments and calibrations for watch enthusiasts. TSAR BOMBA has chosen to collaborate with renowned high-end watch movement manufacturers to jointly design, develop, and produce automatic mechanical movements perfectly matched to TSAR BOMBA watches. Thanks to the strong production capabilities of these renowned manufacturers, the movements in TSAR BOMBA watches offer superior stability and durability compared to watches in the same price range using movements from unknown manufacturers. The TSAR BOMBA movement features a modified, more sensitive rotor that operates even with slight arm movements, extending the power reserve. This high-performance movement offers a power reserve of up to 50 hours (±15%). Its multi-functional design includes chronograph, power reserve indicator, date display, and day of the week dis

The watch industry faced a challenge: finding a material that could replace stainless steel while offering corrosion resistance and lightness without compromising aesthetics or performance. Carbon fiber emerged as a prime candidate thanks to its corrosion resistance, low weight, and versatility. This led to the creation of carbon fiber watches featuring cases, bezels, and straps made from the material. Even large mechanical watches (over 40mm) can be kept under 100 grams, effectively reducing the strain of wearing them daily. Combining a stylish, speed-inspired carbon fiber look with a mechanical movement, these watches are fantastic news for enthusiasts who love mechanical timepieces but desire a lightweight feel.

The entry-level automatic mechanical tonneau watch from TSAT BOMBA—the TB8208A and TB8228A—is priced at only US$399. These two entry-level Tonneau watches are equipped with Citizen's MIYOTA series movement, offering a power reserve of 42 hours (±10%). The skeletonized dial design allows for a direct view of the movement, showcasing the allure of precision mechanics. It highlights the watch's sophistication and mechanical feel while simultaneously expressing your individuality and confident style.
