Is this the same as the older Black Bay 41?

No. The 2023 reference M7941A1A0RU is slimmer, has 21mm lugs, the T-fit clasp and the METAS-certified MT5602-U; the older M79230R was thicker with the MT5602 and a plain folding clasp.

Is this new or pre-owned?

It is a regular Amazon listing from a marketplace seller, not a Luxury Stores pre-owned unit. The rows we read do not state the condition or whether Tudor’s five-year guarantee card is included; ask the seller before buying.

Is a Tudor on Amazon authentic?

It is sold by a marketplace seller with Amazon’s 30-day return window. Amazon does not authenticate the watch; ask the seller for the guarantee card and have it checked inside the window.

What changed in 2023

Tudor rebuilt the 41mm Black Bay in 2023 and kept the name. The case lost more than a millimetre of thickness, the lugs went to 21mm, the bracelet gained the T-fit clasp with five positions of quick adjustment, and the movement became the MT5602-U, which is the old MT5602 with a silicon balance spring, tested by METAS as a Master Chronometer on top of its COSC certificate. That means the finished watch, not just the movement, passed tests for accuracy, resistance to 15,000 gauss, water resistance and reserve.

The burgundy bezel is the original Black Bay colour from 2012, and the gilt-rimmed markers and snowflake hand are the same. No date, as always on this model. It is the Black Bay for someone who wants the full-size watch with the newest movement.

Reading the listing

The listing carries the full reference, M7941A1A0RU-0001, in the title and the model row, and calls it an automatic chronometer with a black dial. The photograph shows the burgundy bezel, the gilt-rimmed markers, the snowflake hand, no date and the three-link bracelet. The case size, thickness, lug width, calibre, its COSC and METAS certifications, reserve, 200 metres and the T-fit clasp are Tudor’s published figures for the reference.

The seller is Watchsavings, a marketplace seller, and the rows we read do not state whether the watch is new with Tudor’s five-year guarantee; ask, and ask for the box and card. Nothing here was measured on the watch.

Buying it on Amazon

This is a regular Amazon listing from a marketplace seller with Amazon’s 30-day return window; it is not a Luxury Stores pre-owned unit and the seller has not published a condition. The second button opens the live search for burgundy Black Bays in case this one has sold.

Black Bays have resold for under new and close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.

FAQ

METAS, the Swiss Federal Institute of Metrology, tests the finished watch rather than the bare movement: accuracy of 0 to +5 seconds a day, resistance to magnetic fields of 15,000 gauss, water resistance and power reserve. The MT5602-U also carries a COSC certificate.
