SMGG21) sets a blue and gray octagonal bezel around a white-framed LCD display for a fresh, understated take on the design. The bezel is also the watch's control center: a simple turn moves the display between modes, just as it did on the much-loved early-1980s original. Numerals drawn in the typeface of the vintage models complete a refined version of a true digital icon.\u003c\/p\u003e\n\n\u003cp\u003eSeiko's A824 digital quartz caliber powers a 1\/100-second chronograph, a counter, dual time, single and daily alarms, day and date displays, an AM\/PM indicator and a battery life display, all within easy reach of that rotating bezel. The 37mm stainless steel case is just 10.6mm thick and pairs with a textured, vintage-inspired steel bracelet and tri-fold push-button clasp, while 100 meters of water resistance makes it a dependable companion for daily wear, travel and time by the water.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating mode-select bezel\u003c\/strong\u003e – the octagonal blue and gray bezel turns to switch between the watch's digital modes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOriginal-style LCD display\u003c\/strong\u003e – set in the same typeface as the vintage models and framed in white.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1\/100-second chronograph\u003c\/strong\u003e – precise stopwatch timing, paired with a handy counter function.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlarms and dual time\u003c\/strong\u003e – single and daily alarms, a second time display, AM\/PM indication and a battery life readout.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100m water resistance\u003c\/strong\u003e – a 10 bar stainless steel case and bracelet secured by a tri-fold push-button clasp.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e SMGG21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollection:\u003c\/strong\u003e Essentials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGender:\u003c\/strong\u003e Men's\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Digital quartz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e A824\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Counter, stopwatch (1\/100-second chronograph), dual time, single and daily alarm, day\/date display, AM\/PM display, battery life display\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material:\u003c\/strong\u003e Stainless steel case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 37 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 10.6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 43.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLug Width:\u003c\/strong\u003e 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e Octagonal blue and gray rotating bezel (mode selector)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e LCD framed in white\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color:\u003c\/strong\u003e White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrystal Material:\u003c\/strong\u003e Hardlex crystal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Stainless steel bracelet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClasp:\u003c\/strong\u003e Tri-fold push button release clasp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 10 bar, 100 meters (330 feet)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTimepiece History\u003c\/h3\u003e\n\u003cp\u003eSeiko's story began in 1881, when founder Kintaro Hattori opened a shop in Tokyo's Ginza district to sell and repair timepieces. In the decades since, Seiko has evolved together with Tokyo, and its watches continue to draw on the culture and design sensibility the city has nurtured for generations. Guided by its founding philosophy of staying \"Always one step ahead of the rest,\" Seiko marks its 145th anniversary in 2026.\u003c\/p\u003e\n\u003cp\u003eThe SMGG21 traces its roots to a Seiko digital watch introduced in 1982 that enthusiasts nicknamed the \"Rotocall.\" Its octagonal rotary switch changed the way wearers moved between functions such as the alarm, timer and stopwatch, letting them change modes with a simple turn of the bezel. That inventive design, together with its popularity among astronauts in the 1980s, when the octagonal design was used on several space missions, earned the Rotocall wide recognition around the world. Seiko has now recreated the design for today, keeping the octagonal case, the rotating bezel and the typeface of the original display while upgrading its performance.\u003c\/p\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":43029743468592,"sku":"SMGG21","price":440.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/1764\/4336\/files\/SMGG21_1_85993b13-b685-4448-b419-333b10813eea.png?v=1793133399","url":"https:\/\/elizaldejewelers.com\/es\/products\/seiko-essentials-digital-quartz-rotocall-smgg21","provider":"Elizalde Jewelers","version":"1.0","type":"link"}
