Engineered under the horological stewardship of the world-renowned Seiko Watch Corporation—which established the Alba brand in Japan in 1979—this reference unites classic diver-inspired tool-watch ergonomics with a sharp, bold high-contrast aesthetic. Celebrated among mechanical watch enthusiasts, collectors of Seiko-family automatics, and sports horology aficionados by its official and community nicknames—the \"Dual-Tone Bezel\", \"Active Automatic\", \"Black Diver\", \"Mechanical Sports\", \"Two-Tone Bezel\", or \"Alba Diver Style\"—this 43.0mm timepiece commands an impressive, athletic presence on the wrist. It pairs a robust solid stainless steel case with a striking dual-tone rotating sports bezel, an anti-reflective deep black dial face, bold applied luminous hour markers, polished luminous hands, a framed date calendar aperture at 3 o'clock, an in-house Japanese automatic movement, a scratch-resistant mineral crystal, a transparent exhibition display caseback, certified 100-meter water resistance, and a solid stainless steel construction. Perfectly calibrated for gentlemen seeking an authentic, self-winding mechanical sports watch that transitions effortlessly from aquatic adventures to smart-casual daily wear. The defining visual centerpiece of this AU4073X1 reference is its high-contrast sports diver aesthetic, anchored by its specialized dual-tone rotating bezel insert. The bezel combines two distinct tones across its elapsed-time scale, accented by crisp numerical calibrations and a luminous triangular zero-marker, framed by a serrated coin-edge profile that provides positive tactile grip during operation. Beneath the crystal sits an expansive, deep black dial face engineered for instantaneous legibility under all ambient conditions. The hour track is lined with applied polished steel indices—featuring bold circular plots and faceted baton markers—generously filled with high-potency luminescent material. Polished sword-style hour and minute hands sweep authoritatively across the dial face, accompanied by an energetic central sweep seconds hand. Positioned neatly at 3 o'clock is a bordered date calendar aperture, delivering practical everyday convenience while preserving balanced dial geometry. Flanked by protective case crown guards and finished with clean geometric lines, the timepiece delivers an unmistakable and confident presence on the wrist. Beneath its athletic exterior, the watch is powered by an in-house Japanese mechanical automatic movement engineered under the exacting manufacturing standards of Seiko Watch Corporation (the proven Calibre Y675 mechanical automatic platform). Operating entirely on kinetic energy captured from the natural motion of the wearer’s arm, this 21-jewel self-winding caliber beats at a steady frequency of 21,600 vibrations per hour (3 Hz) and requires no battery replacements. When fully wound, the mainspring delivers an autonomous power reserve of approximately 41 hours. Turning the watch over reveals a screw-down exhibition display caseback fitted with clear mineral glass, allowing the wearer to admire the mechanical escapement, balance wheel, and oscillating winding rotor in motion. The caliber coordinates central three-hand timekeeping (hours, minutes, sweep seconds) alongside an efficient, synchronized quickset date calendar mechanism operated directly via the 3 o'clock fluted crown. The case is engineered with substantial, contemporary sports proportions, measuring an official 43.0mm in case diameter with a case thickness of approximately 13.5mm, an ergonomic lug contour, and a standard 22mm lug width, ensuring an authoritative, planted, and comfortable drape on the wrist. The solid stainless steel case architecture combines fine circular satin brushing across the upper lug hoods with mirror-polished side flanks and chamfered edges. Dial protection is provided by a scratch-resistant flat mineral crystal glass that shields the dial face against daily abrasions and impacts. Built for an active terrestrial and aquatic lifestyle, the solid stainless steel case incorporates a screw-down exhibition caseback securing a certified 100-meter (10 bar \/ 10 ATM \/ 330 ft) water resistance rating, safely guarding the mechanical movement against swimming, snorkeling, recreational water sports, and heavy rain. The timepiece comes completed on an integrated solid stainless steel multi-link construction featuring brushed outer links and polished center accents, secured by a solid three-fold deployment clasp with a dual push-button safety release.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"MonaWatch","offers":[{"title":"Default Title","offer_id":67595321508154,"sku":"AU4073X1","price":525.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/5858\/3354\/files\/NewProject_640a5999-daf2-496e-b505-416ac89c4b8d.webp?v=1790655543","url":"https:\/\/www.monawatch.com\/products\/alba-active-mechanical-au4073x1-mens-watch","provider":"MonaWatch","version":"1.0","type":"link"}
