Who should buy which.
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.
The Admiral 3-Hand No-Date Titanium Diver (Aurora Green): A buyer looking for a titanium automatic diver with a green no-date dial, sapphire crystal and a bracelet rather than a rubber strap. Choose a shorter or thinner watch if the 49 mm span overhangs your wrist, or a dated version if you rely on a calendar.
Before you order.
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.
At 49 mm lug-to-lug and 13 mm thick, this 40 mm case has a meaningful wrist span. The no-date layout is a plus if you like a clean dial, but it is the wrong variant if a calendar is essential. BODERRY lists $259 as the current sale price before our code; the $299 regular price is separate from the code calculation.
