D1 MILANO UHBJ04 Carbon Reef Ultra Thin 39mm while the supple midnight-black leatherThis watch features a 39mm stainless steel case and a blue brass dial. Protected by anti reflective sapphire glass, the integrated steel bracelet follows the wrist's natural geometry for a comfortable and low profile design. The defining feature of the Ultra Thin is its remarkably slim case. Measuring just a few millimeters thick, this watch challenges the norm by offering a lightweight and comfortable fit without compromising on style or durability.
