Tudor vs Tissot: Which Is Better?

The Tudor Black Bay 58 runs the Calibre MT5402, an in-house automatic built by Kenissi, beating at 28,800 vph (4 Hz) with 27 jewels and a 70-hour power reserve. A manufacture movement at 4 Hz is the traditional luxury-watch spec sheet, and it is the core of what the Tudor premium buys.

Tissot's PRX Powermatic 80 uses the Powermatic 80.111, an in-house Tissot automatic built on an ETA C07.111 base, running at a slower 21,600 vph (3 Hz) with 23 jewels. The trade for that slower beat rate is a longer 80-hour power reserve — the Tissot actually outlasts the Tudor off the wrist by about 10 hours. Tissot's Gentleman Powermatic 80 Silicium adds an anti-magnetic silicon balance spring, a feature normally associated with far more expensive watches.

The Black Bay 58 is a true dive watch: 39mm 316L stainless steel case, domed sapphire crystal, unidirectional bezel, and 200m (20 ATM) water resistance. The PRX Powermatic 80 is an integrated-bracelet sports watch: 40mm 316L steel, scratch-resistant sapphire, and 100m (10 ATM) — plenty for swimming, not rated for diving.

If you specifically want Tissot to match Tudor's dive credentials, the Tissot Seastar 1000 Automatic is rated 300m (30 ATM) with the same Powermatic 80 movement, and sits in the $500–$1,000 band as well.

In our catalogue, every Tissot automatic — PRX Powermatic 80 (40mm and 35mm), Gentleman Silicium, Le Locle, Seastar 1000 — lands in the $500–$1,000 band. The Tudor Black Bay 58 sits in the $2,500–$5,000 band. That gap, several times the price of the Tissot, is the real decision: the Tudor is the better watch on movement pedigree and dive build, but it is not several times more watch by the spec sheet.
