Engineered for discerning professionals who demand absolute, atomic-level timekeeping precision alongside refined aesthetic luxury, this reference represents the pinnacle of Seiko's grab-and-go convenience and autonomous horological engineering. Across global collector communities, horological forums, and Japanese domestic market (JDM) enthusiast circles, it has earned cherished community nicknames—the \"Solar Radio\", \"Champagne Radio\", \"Two-Tone Spirit\", \"Radio Wave\", \"Atomic Champagne\", or \"Classic Solar Radio\"—for its radiant sunburst champagne dial, warm yellow gold-tone accents, ultra-thin 7.8mm case profile, scratch-resistant sapphire crystal, and atomic radio-wave synchronization. It unites a sculpted 316L solid stainless steel case in a tailored 37.6mm diameter with an evocative sunray champagne-gold dial face, polished gold-plated smooth bezel, applied gold-tone indices, an in-house Japanese solar radio caliber, flat sapphire crystal glass, certified 100-meter water resistance, and an integrated solid stainless steel multi-link construction. Perfectly calibrated for gentlemen seeking a luxurious, maintenance-free daily wearer that transitions seamlessly from corporate executive boardrooms and business travel to formal dinners and weekend social gatherings. The defining visual centerpiece of this SBTM170 reference is its luminous, multi-dimensional sunburst champagne dial plate. Finished with an ultra-fine radial brushing technique, the soft golden surface dynamically catches and diffuses ambient lighting into warm, iridescent reflections that convey quiet opulence without overwhelming the wrist. Hidden beneath the dial face are high-efficiency micro-solar cells that absorb natural sunlight and artificial indoor lighting to continuously power the watch. Circling the perimeter are three-dimensional, multi-faceted applied gold-tone baton hour markers that catch light brilliantly from every angle. Slender, mirror-polished gold-tone sword-style hour and minute hands sweep over the face alongside a delicate central sweep seconds hand, delivering crisp, instantaneous legibility against the champagne background. Positioned neatly at 3 o'clock is a framed date calendar aperture linked directly to the caliber's perpetual calendar system. Framing the dial is a fixed, mirror-polished yellow gold-plated solid stainless steel bezel that creates an elegant two-tone contrast against the silver-tone case and multi-link construction. Beneath its tailored exterior, the watch is driven by Seiko’s dedicated in-house Calibre 7B52 Japanese solar-powered radio-controlled quartz movement, engineered and manufactured at Seiko’s horological facilities in Japan. Operating on atomic radio-frequency technology, the caliber automatically synchronizes with Japan's official standard radio time transmitters (JJY stations on 40 kHz and 60 kHz frequencies) to achieve atomic-clock precision, eliminating daily deviations. When operating outside radio reception range, the quartz crystal maintains a standalone precision tolerance of ±15 seconds per month. Utilizing advanced photovoltaic technology, the movement converts any light source into electrical energy stored in a secondary rechargeable lithium-ion cell, completely eliminating the need for periodic battery replacements. The movement provides approximately 6 months of autonomous operation on a full charge, extending up to 1.5 years in power-saving mode. The Calibre 7B52 features an integrated Full Auto-Calendar (Perpetual Calendar programmed to December 31, 2099) that automatically accounts for odd and even months as well as leap years, an automatic hand position alignment function, a time difference correction function, an automatic and manual radio reception function, reception result display, an overcharge prevention function, and an instant-start function. The case is engineered with classic, mid-century dress proportions, measuring an official 37.6mm in case diameter with an ultra-slender case profile thickness of just 7.8mm, a compact 44.6mm lug-to-lug distance, and a versatile 20mm lug width. Weighing approximately 105.0 grams, the watch sits exceptionally flat and balanced on the wrist, offering a featherlight, low-profile drape that slips effortlessly beneath tailored dress shirts and jacket cuffs. The solid 316L stainless steel case architecture combines vertical hairline satin brushing across the lug hoods with mirror-polished flanks and gold-plated bezel accents. Dial protection is provided by a premium flat sapphire crystal, offering superior scratch resistance and crystalline optical clarity. Built for dependable daily resilience, the solid stainless steel case features an ergonomic fluted pull-out crown at 3 o'clock, flush radio-reception setting buttons, and a solid screw-down caseback, securing an impressive 10-bar (100 meters \/ 330 ft) water resistance rating, making it completely safe for swimming, daily hand washing, and heavy rain. The timepiece comes completed on an integrated solid stainless steel multi-link construction featuring satin-brushed surfaces and polished accents, secured by a sturdy one-push three-fold deployment clasp with micro-adjustment capability.\u003c\/p\u003e","brand":"MonaWatch","offers":[{"title":"Default Title","offer_id":67713370849594,"sku":"SBTM170","price":1005.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/5858\/3354\/files\/NewProject_8047af55-5866-4525-90d9-8c56c987a454.webp?v=1792162725","url":"https:\/\/www.monawatch.com\/products\/seiko-selection-solar-radio-sbtm170-mens-watch","provider":"MonaWatch","version":"1.0","type":"link"}
