The 39mm steel case, the vintage-inspired matte black dial, the gilt minute track and indices, and the in-house calibre MT5402 movement together represent the strongest value-to-quality proposition in Swiss diver watches at any price point.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCase:\u003c\/strong\u003e 39mm stainless steel with brushed and polished finishing. Domed sapphire crystal. Unidirectional 60-minute timing bezel with anodised aluminium insert. Screw-down crown. 200 metres water resistance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDial:\u003c\/strong\u003e Matte black with applied gilt indices and Snowflake hands. The vintage-inspired design references the original 1958 Tudor Submariner reference 7924.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e In-house calibre MT5402, COSC-certified chronometer. 70-hour power reserve. Silicon hairspring with anti-magnetic resistance. 28,800 vph operating frequency. The MT5402 is the heart of the Tudor manufacture movement programme that has replaced the previous ETA-sourced calibres across the modern Tudor range.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBracelet:\u003c\/strong\u003e Steel five-link riveted bracelet with Tudor folding clasp. Also available with vintage-inspired leather or rubber strap options depending on production year.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat separates the 79030N:\u003c\/strong\u003e The Black Bay 58 sits at the centre of Tudor's design discipline. At 39mm, it deliberately counter-positions the modern industry trend toward 42mm and larger cases. The pricing has remained anchored to retail across multiple production years, which makes the pre-owned market for the 79030N one of the tightest spread-to-retail markets in Swiss diver watches.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePre-owned market position:\u003c\/strong\u003e The Black Bay 58 79030N trades around $2,800 to $3,200 for clean full-set examples in 2026. The reference has not been swept into speculative secondary market pricing that has affected the Rolex Submariner equivalents, which makes it the most defensible diver watch purchase under $3,500 currently available.\u003c\/p\u003e\n\n\u003cp\u003eFor collectors entering the modern Tudor line for the first time, the Black Bay 58 79030N is the canonical starting point. For collectors who already own a Submariner or other steel diver, the 79030N is the smaller-cased counterpart with comparable engineering and a meaningfully tighter wrist proportion.\u003c\/p\u003e\n\n\u003cp\u003eEvery Tudor in our inventory is inspected in-hand by our physician-led vetting team. Movement function, dial originality, bezel insert condition, and bracelet integrity are documented before listing.\u003c\/p\u003e","brand":"Tudor","offers":[{"title":"Default Title","offer_id":52968763752758,"sku":null,"price":2800.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/4225\/8742\/files\/Photoroom_20250513_210802_ce401bc8-b193-4f04-8693-3bac15f9fa88.jpg?v=1757892422","url":"https:\/\/hrockluxury.com\/products\/tudor-black-bay-58-79030n-steel-black-dial","provider":"Honeyrock Luxury Trades ","version":"1.0","type":"link"}
