The Tudor Black Bay 54 “Lagoon Blue” (reference number M79000-0001) differs from the original Black Bay 54 in several key ways, and these changes work together to create a softer, more modern expression of the brand’s most fan-favorite dive watch. Crafted from stainless steel, the Biwan 54 “Laze” has the same proportions as the first edition, measuring 37mm in diameter and 11.2mm thick. Again, a domed sapphire crystal protects the dial, while the back of the watch features a solid screw-down caseback. As you’d expect from a Tudor Biwan diver, the winding crown at 3 o’clock also screws into the middle case, contributing to the 200m water resistance. <p>replica Patek Philippe 175th-Anniversary</p>
