T023 V3.1 40mm PT5000 Automatic Dive Watch (Cream White)
or T028 37mm PT5000 Automatic Dive Watch (Black Dial)?
Both exact THORN variants are listed at $199 and cart-tested at $194 after SEBASTIANBASSOL, before shipping and taxes. Choose the T023 V3.1 Cream White for its warmer 40 mm dial, thinner 12.3 mm case and tool-less bracelet adjustment. Choose the T028 Black if you want a narrower 37 mm dial and the pictured leather strap plus two interchangeable bezel inserts. Both share a 46.6 mm lug-to-lug span, so the T028 is narrower across the dial, not shorter over the wrist.

Who should buy which.
The T023 V3.1 40mm PT5000 Automatic Dive Watch (Cream White): A buyer who wants a vintage-inspired automatic diver with a cream dial and a bracelet that can be resized without a conventional link-removal tool. Choose a diver with explicit ISO 6425 certification if that documented standard is a requirement. The Citizen Promaster BN0165-55L is a higher-priced, light-powered alternative with a published ISO listing and a separately tested retailer code.
The T028 37mm PT5000 Automatic Dive Watch (Black Dial): 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. 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.
Before you order.
The case measures 40 mm across, but its 46.6 mm lug-to-lug span is more useful for checking wrist fit. At 12.3 mm thick and about 129 g on the listed bracelet, it has noticeable presence; compare the span and bracelet length with a watch that already fits.
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.
