Tudor Black Bay One 36mm Steel Light Champagne Diamond Dial M79640-0006 - BRAND NEW

The Tudor Black Bay One 36 reference M79640-0006 is one of the most compelling entries in Tudor's celebrated Black Bay family — a line that has defined the brand's modern identity since its relaunch and grown into one of the most sought-after collections in the mid-luxury watch market. Sized at 36mm in stainless steel, the Black Bay One 36 was conceived to bring the collection's bold, heritage-infused design language to a broader audience, offering a case diameter that wears beautifully on a wide range of wrist sizes without sacrificing any of the visual authority the Black Bay name commands.

The dial of the M79640-0006 is finished in a warm light champagne tone that immediately distinguishes it from the more utilitarian colorways typically associated with dive-inspired sport watches. Diamond-set hour indices replace the conventional applied markers, catching light at every angle and introducing a layer of refined luxury that elevates this reference above a straightforward tool watch into genuine fine-watch territory. The result is a dial that reads with confidence in both candlelight and daylight — equally at home at a business dinner or a weekend brunch.

The case is crafted from stainless steel and measures 36mm across, a diameter that Tudor has executed with particular care in the Black Bay One line. The stainless steel bezel carries the characteristic profile of the Black Bay family, with clean lines that frame the dial without overpowering it. On the wrist the watch sits with a satisfying solidity that speaks to Tudor's rigorous build standards, and the steel bracelet — which links cleanly to the case — provides a confident, integrated look while remaining comfortable for all-day wear.

Tudor has long distinguished itself by pairing accessible price points with movements manufactured to exacting standards, and the Black Bay One 36 continues that tradition. The watch is presented here in brand-new condition, meaning it arrives unworn with all the integrity of a fresh factory example — an important consideration for collectors who value the full originality of a reference and for buyers who intend to register the international warranty directly in their own name.
