Like most Tudor watches, the Black Bay 58 925 is a great value for money.

Thoughtfully executed, this watch focuses on simple quality and reliability rather than decoration and refinement. It doesn’t excel in a single aspect, but every aspect of the luxury replicas watch is consistently executed to an exceptional standard, with a reassuring consistency in quality that makes the whole greater than the sum of its parts.

The 925 is one of the brand’s most adventurous watches in terms of materials and design. The silver case is interesting and unique among its peers. Combined with the taupe bezel and dial – giving a diver’s watch an uncharacteristically understated look – and the 925 makes it clear that Tudor is aware of its growing audience base and maintains its signature styling cues diversify its products.

The movement visible under the 925 sapphire case back, known as the MT5400, is nearly identical to the MT5402 in BB58 steel, except for a wider base plate to fill the holes in the transparent back (and possibly allowing thinner case walls to lighten the precious metal case). weight).

The open caseback sparked a lot of discussion during the launch of the 925 and its compatriots, as Tudor showed how rare such a movement is. immatation watches

While this isn’t the first Tudor watch with a caseback—a title that belongs to the lesser-known North Flag—the brand has come a long way since its launch in 2015 (which, by the way, is the first a Tudor watch with an in-house movement)). So it feels like the 925 and 18k are the first Tudor watches with a display.

The back of the display showcases a clean and uncluttered industrially manufactured movement.

In terms of decoration, the MT5400 is low-key. It’s finished like any other Tudor in-house movement (apart from Black Bay Ceramics), with the bridges and bridges sandblasted and the rotors radially brushed for a clean and simple look.

Smaller details are paid attention, but in a basic way. The chamfers on the bridges and the countersunk holes for the screws and jewels are stamped, then the entire part is sandblasted.

It almost feels like the Tudors deliberately chose not to embellish the movement, and it was a missed opportunity. Even modest tweaks like a fancier rotor or a higher-contrast finish can make a big difference, as evidenced by the movement inside the latest-generation Chanel J12, powered by an almost identical movement from the same factory Powered by (majority owned by replica Tudor).

That said, the open caseback can reveal that it’s an in-house mechanical movement, which is actually an excellent one. In addition to a three-day power reserve, it has a silicon hairspring that eliminates the possibility of magnetizing the hairspring, allowing the watch to run fast at low amplitudes, up to a few hours a day.

It also boasts details such as a fully balanced bridge with free spring balance. The full bridge offers better shock resistance, while the latter offers better stability over time as well as improved isochronism because there are no adjustment pins to interfere with the hairspring. This is important because these features are not common in watches in the same price range, such as those from Grand Seiko.

The technical quality of the movement is proven by Tudor’s own certification process, which guarantees a maximum deviation of +4/-2 seconds per day, a standard that is also superior to most competitors in the same price range. And the movement has also passed the COSC test and certification.
