Celebrated worldwide among high-horology purists, connoisseurs of Japanese mechanical complications, and luxury collectors by its iconic series nicknames—the \"M45\", \"Mechanical Moon Phase\", \"Pleiades\", \"Subaru\", or \"Semi-Skeleton Moon Phase\"—this 41.0mm masterpiece draws poetic inspiration from the Messier 45 (Pleiades) star cluster, revered in Japanese folklore as \u003ci\u003eSubaru\u003c\/i\u003e. It unites high-end artistic dial craftsmanship with in-house Japanese manufacture movement engineering, pairing an exquisitely sculpted SUS316L stainless steel case with a multi-layered textured midnight-blue gradation dial, a semi-skeleton open-heart window at 9 o'clock, a fan-shaped 50-hour power reserve indicator at 12 o'clock, an integrated astronomical moon phase aperture with an analog date pointer at 6 o'clock, elegant Roman numeral indices, dual-curved sapphire crystal with anti-reflective coating, a 50-meter water resistance rating, and a solid stainless steel construction. Perfectly calibrated for discerning gentlemen seeking a sophisticated, mechanical complication timepiece that exudes intellectual prestige and timeless luxury. The defining visual highlight of this RE-AY0103L reference is its captivating, starry night-sky dial architecture. The deep blue dial face features an intricate stamped textured pattern that subtly depicts the shimmering stars and cosmic dust of the Pleiades open cluster. The dial transitions from a deep midnight blue at the center to an intense black around the outer edge, mimicking the vastness of outer space. Anchoring the dial at 6 o'clock is an artisan moon phase complication, featuring a rotating astronomical disc adorned with a golden crescent moon and twinkling stars surrounded by a concentric date calendar track. At 9 o'clock, a circular semi-skeleton aperture reveals the ticking balance wheel, ruby jewels, and escapement of the mechanical movement. The upper hemisphere is balanced by a fan-shaped power reserve indicator at 12 o'clock tracking remaining spring tension up to 50 hours. Slender skeletonized leaf hands glide gracefully over polished applied Roman numeral hour markers, ensuring instantaneous readability. Protected by an ultra-clear dual-curved sapphire crystal treated with SAR (Super Anti-Reflective) coating, the watch delivers breathtaking optical depth and a majestic wrist presence. Beneath its celestial exterior, the watch is powered by Orient Star’s premier in-house Caliber F7M62 mechanical automatic movement, entirely designed, engineered, and hand-assembled in Japan. Built to the highest standards of Japanese horological finishing, this 22-jewel caliber beats at a steady frequency of 21,600 vibrations per hour (3 Hz) and delivers exceptional timing precision, calibrated to a tight factory specification of +15 to -5 seconds per day. The movement incorporates an autonomous power reserve of 50 hours on a full wind, with remaining kinetic potential continuously monitored via the analog sub-dial gauge at 12 o'clock. Featuring bidirectional automatic rotor winding, manual hand-winding capability, and a second-hand hacking mechanism for down-to-the-second synchronization, the caliber flawlessly coordinates running hours, minutes, central seconds, a date pointer hand, and the astronomical lunar cycle mechanism. The case is crafted from premium, corrosion-resistant SUS316L surgical-grade stainless steel, featuring balanced proportions measuring an official 41.0mm in case diameter, a profile thickness of 13.8mm (accommodating the domed crystal and multi-tier complications), a 49.0mm lug-to-lug contour, and a standard 20mm lug width. The exterior case finishing showcases a refined interplay of mirror-polished chamfers and satin-brushed lug flanks. The dial is shielded by a premium dual-curved sapphire crystal with Orient Star's proprietary SAR (Super Anti-Reflective) coating on both surfaces, suppressing 99% of surface glare to make the glass virtually invisible. Turning the watch over reveals a screw-down exhibition display caseback fitted with a sapphire crystal, showcasing the circular Geneva striping (Côtes de Genève), perlage, and gold-engraved Orient Star logo on the skeletonized winding rotor. Designed for dependable everyday luxury, the case provides a certified 50-meter (5 bar \/ 5 ATM \/ 165 ft) water resistance rating, safely guarding the movement against incidental hand washing, rain, and light water splashes. The timepiece comes completed on an integrated solid SUS316L multi-link stainless steel construction featuring brushed links with polished intermediate bars, secured by a solid tri-fold deployment clasp with a dual push-button safety release.\u003c\/p\u003e","brand":"MonaWatch","offers":[{"title":"Default Title","offer_id":54117901926714,"sku":"RE-AY0103","price":7210.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/5858\/3354\/files\/NewProject_89b4472f-b04e-42e9-91d3-9c44a82f804a.webp?v=1790212801","url":"https:\/\/www.monawatch.com\/products\/orient-star-classic-m45-f7-mechanical-moon-phase-re-ay0103l-mens-watch","provider":"MonaWatch","version":"1.0","type":"link"}
