Bronze develops its own character over time through natural oxidation, giving each piece a gradually evolving appearance. A fixed bezel, scratch-resistant sapphire crystal, and water resistance to 100 meters round out the case's practical credentials.\u003c\/p\u003e\u003cp\u003eThe green dial is fitted with index hour markers and luminescent hands for clear readability across varying light conditions. Inside runs a self-winding mechanical movement — the B21, developed in collaboration with La Joux-Perret — operating at 28,800 vph with a 55-hour power reserve and 30 jewels. The chronograph function offers 1\/4-second timing resolution and a 60-minute counter.\u003c\/p\u003e\u003cp\u003eThe watch is presented on a brown calfskin strap secured by a fold clasp, and this 2025 example is unworn and accompanied by its original box and papers.\u003c\/p\u003e","brand":"It's That Time","offers":[{"title":"Default Title","offer_id":49919807520997,"sku":null,"price":49500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/5600\/7653\/files\/product228-breitling-top-time-b21-nb21251a1l1x1-43mm-bronze-green-dial-image1.jpg?v=1782915270","url":"https:\/\/itsthattimenyc.com\/products\/breitling-top-time-b21-nb21251a1l1x1-43mm-green-bronze-leather","provider":"It's That Time ","version":"1.0","type":"link"}
