Quick TakeForget bulky divers that look out of place anywhere but the deep end. The SUB 300 Beta Searambler struts a refined line between serious underwater capability and urban cool. It's got the guts – 300 meters of water resistance, a helium escape valve, and that ultra-tough ceramic bezel – but wears it with unexpected sleekness thanks to its slimmer 11.95mm profile. The sunray dial, shimmering with a subtle wave pattern, catches the light just right, whether that's dappled sunlight filtering through the waves or the ambient glow of your favorite city spot. The Searambler finish gives it that bright, almost tool-like clarity DOXA is known for, but the overall package feels sophisticated. You get the choice: classic cool with the 'Beads of Rice' bracelet, or modern sportiness with the FKM rubber, both with that handy ratcheting extension. It’s a DOXA, so it’s built tough, runs on a reliable Swiss automatic heart, and doesn’t compromise on its diving heritage, yet it feels perfectly adapted for adventures above sea level too.
DescriptionThe timepiece designated as Reference 830.10.021.10, known as the SUB 300 Beta Searambler, is constructed with specific dimensional parameters and material specifications optimized for performance. Its case is fabricated from stainless steel, featuring a diameter measurement of 42.50 millimeters and a lug-to-lug distance of 44.50 millimeters. A notable characteristic is the reduced case height, engineered to 11.95 millimeters, contributing to a more streamlined profile compared to antecedent models within the lineage. Structural integrity necessary for underwater application is achieved through the incorporation of a screw-down crown mechanism and a solid stainless steel screw-down case back. These elements are crucial in attaining the specified water resistance rating of 30 atmospheres, which corresponds to a depth capability of 300 meters or 984 feet. Protection for the dial interface is provided by a sapphire crystal, selected for its high degree of scratch resistance, ensuring optical clarity and durability under demanding conditions. The case design facilitates the attachment of either a bracelet or strap via lugs spaced 20.00 millimeters apart. This configuration maintains compatibility with standardized fastening systems while ensuring secure attachment during vigorous activity or underwater excursions. The external architecture prioritizes robustness and functional sealing against environmental ingress.
Internal mechanical operation and time indication functions are governed by a Swiss-manufactured automatic, self-winding movement. This caliber operates at a frequency of 28,800 vibrations per hour (equivalent to 4.0 Hertz), a standard rate for contemporary precision timekeeping instruments, balancing accuracy with component longevity. When fully wound, the movement provides a power reserve autonomously for approximately 38 hours. As specified, the movement incorporates decorative finishing applied by DOXA, adding an aesthetic refinement visible should the case back permit viewing, although this model utilizes a solid back. Time is displayed through central hour, minute, and second hands, supplemented by a date complication presented via an aperture on the dial. User interaction for time setting and date adjustment is managed through the aforementioned screw-down crown. A critical functional component for diving applications is the unidirectional rotating bezel. This safety feature, rendered in black ceramic for enhanced durability and scratch resistance, is marked with a scale calibrated in meters, allowing for the tracking of elapsed time underwater. Furthermore, the inclusion of a helium release valve addresses the needs of saturation diving, enabling trapped helium molecules to escape the watch case during decompression, thus preventing potential damage to the crystal or case integrity. The dial itself features a sunray finish overlaid with a stamped wave structure, creating a distinct visual texture. Attachment options include a stainless steel "Beads of Rice" bracelet or an FKM rubber strap, both secured with a folding clasp incorporating a ratcheting wetsuit extension for adjustability over dive suits.
