TUDOR Black Bay 58 18K

In 1958, Tudor launched its first generation of dive watches, model 7924, also known as the "Big Crown." The Black Bay 58 is named after the year this dive watch was launched, inheriting many of its aesthetic features. This year, a burgundy timepiece certified by the Swiss Federal Institute of Metrology (METAS) as a Master Chronometer has joined the Black Bay 58 collection. This is the first time this model has been paired with a five-link stainless steel bracelet.
