Quality and Durability

One major comparison between the Tudor Pelagos and the Tudor Black Bay is its stainless steel case measure. The prior is only available in 42 millimeters, while the Tudor Heritage Black Bay can be bought in either 32, 36, 42, or 43-millimeter variants.

Nonetheless, these two diver watches possess similar lug to lug length, which both fit six to seven-inch wrists. In terms of the lug width, the Tudor Black Bay’s bracelet tapers down a little more toward the clasp compared to the Pelagos.

Additional Features

Both the Black Bay and the Tudor Pelagos have the same in-house movements, which can hand-wind and hack the second hand. These two dive watches also provide a high frequency of 28,800 bhp and a power reserve of up to 70 hours. 

Both the Black Bay and Pelagos offer accuracy of -4 to +6 seconds per day, making both watches COSC-certified. When it comes to the date complication, the Pelagos only includes the MT5612. This movement also offers an extra jewel, bringing up a total amount of 26. However, the jewel only serves aesthetic purposes, but the reliability and accuracy of both movements are the same. 


Tudor offers a five-year warranty, which covers any malfunction that isn’t part of normal wear and tear. They also offer a two-year service warranty for those who got their watches serviced by Tudor or an Authorized dealer.

In January 2020, Tudor upgraded their two-year warranty up to five years. This advancement places Tudor’s protection length on par with Omega and Rolex.

What Do People Say About It?


Thomas Hearns rated the Tudor Heritage Black Bay a good star rating and described it as a “killer value.” He shared in the comments section, “As an avid collector of dive watches, I can say that the entire Tudor line is superb, especially with their new in-house movement that can maintain a crazy 70-hour power reserve. 

This watch is a perfect size, its relation to Rolex is obvious. I am not a gold fan of wristwatches but the very subtle outlines of the dots and hands add some great sizzle to this piece. 

I own three black bays: one with the older ETA movement, and two with the new movement. If there is one thing I am not crazy about it’s the riveted bracelet, but I am in the minority on this. The older versions have the bracelet with no rivets which I think is cleaner. However, of the three I won, this one gets the most wear.”

For the Pelagos, Thomas M. Allen rated the watch a good star rating as well. “Better than I expected. Extremely comfortable and being titanium, it’s light on your wrist,” he wrote.

“This Tudor Pelagos keeps better time than my Rolex. I used to think that Tudor was just a baby Rolex, but I think Rolex needs to be taught by the people at Tudor.”


The Watch Collection Strategy filmed a YouTube video reviewing the Tudor Heritage Black Bay. They claimed that the watch is a “bargain in the grand scheme of things in the watch collecting hobby.”

One feature they admire about the Heritage Black Bay watch is the craftsmanship and attention to detail, making it worth the purchase despite its hefty price. 

“After putting it on the macro lens, I can tell you this: the finish is on par with their bigger brother, Rolex, despite being half the price.” They claim that the finishing is great. No dust or foreign material can be found inside the dive watch.

The Black Bay is also suitable to be an everyday watch thanks to its in-house caliber and 70-hour power reserve at a COSC certified. Compared to the Submariner, they described the Black Bay as a more relaxed and laid-back watch.
