The quick answer.
Thorn Watches T028 37mm PT5000 Automatic Dive Watch (Black Dial) is a 37 mm diver watch at $194 after code SEBASTIANBASSOL (before code $199). We recommend it for a buyer who wants a black-dial automatic diver in a vintage-leaning 37 mm case, with a warm bezel and an included alternate strap-and-bezel kit.
Why it belongs on the shortlist.
The T028 earns its place through a specific combination: a smaller 37 mm diameter, a black dial with a warm brown bezel, sapphire crystal and a 200 m manufacturer rating. We like that the selected bundle gives its owner an alternate bezel and strap, so the vintage diver look can change without buying a second watch. The tested $5 code makes the current $199 item a $194 purchase before shipping and taxes.
The brown bezel gives the black dial a vintage character.
The black dial and bronze-brown bezel create a warmer combination than the usual black-and-steel diver palette. Large Arabic numerals, luminous hands and a clean no-date layout keep the face easy to read. We would pick this version if you want a small-case diver that still has a clear point of view on the wrist.
The selected package adds real options.
THORN’s official image for the black variant shows the steel-bracelet watch alongside a leather strap and two interchangeable bezel inserts. That expands the ways to wear this design: the bracelet keeps a tool-watch feel, while the leather strap changes the look for drier, less active days. Confirm the selected Black option at checkout so the package matches the one shown here.

Check the full footprint, not only the 37 mm case.
THORN lists a 37 mm diameter, 46.6 mm lug-to-lug span, 13.2 mm thickness and 20 mm lug width. The length and thickness are substantial beside the small diameter, so compare all three measurements with a watch that already fits. The 20 mm connection is straightforward for standard straps, unlike an integrated bracelet.
A practical specification package at the tested price.
THORN lists a PT5000 automatic, anti-reflective sapphire and 200 m / 20 ATM water resistance. That specification, plus the spare bezel and strap, gives the T028 a clear reason to sit at $199 before code. No rated reserve or ISO dive certification is stated on the product page; we treat both as unknown and use the 200 m figure as THORN’s rating.

Before you choose
A 37 mm diameter does not make this a flat-wearing watch: the 46.6 mm lug-to-lug span and 13.2 mm thickness deserve a fit check.
Who it suits.
A buyer who wants a black-dial automatic diver in a vintage-leaning 37 mm case, with a warm bezel and an included alternate strap-and-bezel kit.
When to choose something else.
Choose a thinner or shorter-span watch if you want a low-profile cuff fit; choose a model with formal dive certification if certification is a purchase requirement.
Warranty, returns and ownership.
The current T028 listing confirms the Black variant and its bundle but does not give a product-specific return or warranty term in the details we used. Check THORN’s current warranty and return conditions before ordering, particularly if those terms matter to your decision.
