Today’s offering showcases this Tudor Black Bay Fifty-Eight Navy Blue Sub reference 79030B in collector new condition with Tudor pouch, service papers, and original purchase warranty card.

Launched in 2020, it pays tribute to Tudor’s heritage of professional diving instruments while offering cutting-edge modern performance.

Our example is Collector New—purchased by a collector and either completely unworn or only tried on. To the naked eye it presents as brand new, with hardly even any handling wear. In fact, we have sold unsold Rolex authorized dealer-stock watches that showed more wear than this one. It was purchased by a wealthy collector who often did not wear his watches. It is gift quality.

Its 39mm case, slightly more compact than the standard Black Bay, makes it extremely versatile and wearable on a wide range of wrists. The deep navy blue dial and bezel recall the “Snowflake” Tudors issued to the French Marine Nationale in the 1970s, while its bold square-tipped hands and domed crystal speak clearly to vintage inspiration.

Inside beats Tudor’s in-house MT5402 caliber, a chronometer-certified movement with silicon balance spring, 70-hour power reserve, and robust anti-magnetic properties. It represents Tudor’s step into full independence, no longer relying on ETA ébauches.

The authorized Rolex and Tudor dealer who sold the watch to us included a Tudor pouch with it.

Because the watch initially had an timekeeping issue, it was re-serviced by Rolex USA under its warranty just a few months after it was purchased new. It has been unopened and unaltered since leaving Rolex. We have re-tested it, and it is keeping as new time making it ready for immediate enjoyment.

We also have a Collector New Tudor “Pepsi” GMT we acquired at the same time.

As mentioned accompanying the watch are a Tudor pouch, papers, and original purchase warranty card.

Included with the purchase is a new Connoisseur of Time two-year warranty on the movement and its function and a new timing certificate attesting to the watch’s performance.
