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 Promaster Automatic Blue Dial (NY0086-16L): A buyer who wants an automatic blue-dial Promaster with day-date convenience, a rubber strap and a manufacturer-listed 200 m / ISO 6425 dive specification. Choose a smaller watch if 42 mm is too wide for your wrist, sapphire if you want a harder crystal, or a solar model if avoiding periodic mechanical servicing is the priority.
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 42 mm, this is a full-size diver, and Citizen does not publish lug-to-lug on the official regional page. The retailer lists 12 mm thickness; Citizen specifies crystal glass rather than sapphire. Check the span and crystal material against your priorities before ordering.
