{"product_id":"citizen-promaster-dive-eco-drive-2026","title":"Citizen Promaster Dive Eco-Drive 2026","description":"\u003cp\u003eThe Promaster Dive is Citizen's answer to a watch that works as hard underwater as it does on dry land, pairing genuine ISO dive-watch performance with a case built for daily rotation. It runs on Citizen's Eco-Drive system, which draws power from any light source — indoors or out — so there's never a battery to track down or replace.\u003c\/p\u003e\n\u003cp\u003eThe 40.6mm case is finished in silver-tone stainless steel and paired with a black unidirectional bezel for tracking elapsed dive time. A matte white dial keeps legibility sharp, with a date window sitting at 3 o'clock. Up top, an anti-reflective sapphire crystal resists impact and scratching while cutting glare. It's fitted to a polyurethane strap with a buckle closure, rated to 200m of water resistance, and comes in at a wearable 84 grams.\u003c\/p\u003e\n\u003cp\u003eInside is the E118 Eco-Drive caliber, a light-powered movement that stores energy continuously rather than depleting like a standard battery-driven quartz movement. It drives a straightforward 3-hand-with-date layout, keeping the focus on dive-ready function over added complications.\u003c\/p\u003e","brand":"Citizen","offers":[{"title":"White - BN0265-00A","offer_id":44670137040962,"sku":"BN0265-00A","price":340.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0014\/6158\/3938\/files\/2026_07_Citizen_BN0265-00A_index01.jpg?v=1785787094","url":"https:\/\/windupwatchshop.com\/en-gb\/products\/citizen-promaster-dive-eco-drive-2026","provider":"Windup Watch Shop","version":"1.0","type":"link"}
