The quick answer.
Citizen Promaster Automatic Blue Dial (NY0086-16L) is a 42 mm diver watch at $251.91 after code SEBASTIANBASSOL (before code $279.90). We recommend it for 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.
Why it belongs on the shortlist.
The Promaster earns its price through a purposeful mix: Citizen’s 8204 automatic with day and date, a 42-hour stated reserve, screw-down crown and caseback, urethane strap and 20 bar rating with ISO 6425 listed by Citizen. We like the blue dial because it adds color to a high-legibility tool-watch layout without changing what the watch is for. The code test makes the exact retailer listing more compelling, while shipping and taxes remain outside the tested item total.
A Promaster diver that stays easy to understand.
The NY0086-16L keeps to familiar diver-watch essentials: a rotating elapsed-time bezel, luminous markers, a day-date window and a black urethane strap. The blue face and red-and-blue bezel add color without making it difficult to read. We recommend it to buyers who want that established tool-watch character in an automatic format.
The movement makes rotation easier.
Citizen lists its Cal. 8204 automatic movement with a 42-hour power reserve and day-date indication. The reserve is useful if you leave the watch unworn for a day or two between wears, while the calendar adds convenience to a regular rotation. These are manufacturer specifications; we have not measured an individual example.
A 42 mm case needs a wrist check.
Citizen publishes a 42 mm case and a 20 mm strap connection. Its regional page does not give lug-to-lug; the retailer states 12 mm thickness. Citizen lists the urethane strap for a 120–210 mm wrist range. Compare the case span with a watch you wear comfortably and check the strap range before buying.
The dive specification is part of the buying case.
Citizen lists 20 bar / 200 m water resistance and ISO 6425 for this Promaster reference, alongside a screw-down crown and caseback. We consider that a useful, clearly documented purpose for the watch, while leaving service and water use to Citizen’s operating guidance. Mineral crystal is the main material compromise beside the dive specification.

Before you choose
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.
Who it suits.
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.
When to choose something else.
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.
Warranty, returns and ownership.
Watches of America lists a one-year retailer warranty and a 30-day return window for eligible items; its conditions and a restocking fee may apply. Citizen’s regional warranty terms may differ, and the retailer listing does not establish that Citizen coverage applies to this order. Confirm the written coverage and return conditions with the seller.
