Its galvanized, white silver-plated dial eliminates the traditional small seconds sub-dial to deliver an unadorned two-hand layout. Finished with mocha-brown typography and slender gold-colored hands, the dial face maintains exceptional clarity within a low-profile architectural frame.\u003c\/p\u003e\n\u003cp\u003eConstructed with a case height of 6.1 mm and a lug-to-lug length of 38.5 mm, the watch offers proportioned ergonomics suited for slimmer wrists. Sapphire crystal glass protects the dial, while a water resistance rating of 5 atm (splash-proof) provides reliable daily durability. The timepiece is paired with an 18 mm beige vegan velour remborde strap, complementing the warm metallic tones of the hands and case.\u003c\/p\u003e\n\u003cp\u003eInside, the hand-wound in-house caliber DUW 4001 Duo provides manual timekeeping. Measuring 2.6 mm in height and 23.3 mm (10 ½ lines) in diameter, this specialized caliber features a modified second wheel with a smaller staff engineered specifically for two-hand configurations, combining mechanical accuracy with an extraordinarily thin movement profile.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCase: 27.5 mm x 27.5 mm stainless steel (6.1 mm thick) with stainless steel back\u003c\/li\u003e\n\u003cli\u003eCrystal: Sapphire crystal\u003c\/li\u003e\n\u003cli\u003eDial: Galvanized, white silver-plated, gold-plated hands\u003c\/li\u003e\n\u003cli\u003eMovement: Nomos Glashütte Alpha Duo (manual)\u003c\/li\u003e\n\u003cli\u003ePower reserve: 43 hours\u003c\/li\u003e\n\u003cli\u003eWater Resistance: 30 meters (splash-proof)\u003c\/li\u003e\n\u003cli\u003eStrap: Vegan velour remborde beige (lug width 18 mm)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Nomos Glashütte","offers":[{"title":"Default Title","offer_id":11072058982447,"sku":"405","price":2090.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2930\/0774\/products\/0405_tetra_27_duo-2d-front.jpg?v=1594025891","url":"https:\/\/topperjewelers.com\/products\/nomos-glashutte-405","provider":"Topper Fine Jewelers","version":"1.0","type":"link"}
