This is a new release news post. Prices below are what Citizen listed at the time of writing. They can change, so confirm the live brand page before you buy.
Citizen has listed a Promaster Dive Uncharted Waters limited edition trio on its US store. The watches are presented with sport fishing champion Peter Miller under the product name Promaster Dive x Peter Miller. All three are Eco-Drive divers with sapphire crystals and a 200 meter water resistance rating. I checked Citizen’s US and Canada product pages on 11 November 2026 at about 8.30am Manila time.
At the time of writing, Citizen US listed the BN0251-04L at $425.00. The two steel bracelet models, BN0276-54L and BN0270-51E, were listed at $450.00 each. Citizen Canada listed the strap model at 595.00 Canadian dollars and the bracelet models at 695.00 Canadian dollars each. I did not find a matching Amazon US listing for any of the three references on this check. The live Citizen product pages are the place to confirm price and availability.
The Specs That Matter
Citizen’s US and Canada spec tables agree on the shared hardware for movement, case width, crystal and water resistance.
- Movement listed as Eco-Drive caliber E118 on the US and Canada spec tables for all three references. Citizen describes Eco-Drive as powered by any light source, with no battery replacement needed.
- Crystal listed as sapphire on all three tables, with Citizen’s usual note on scratch resistance and hardness.
- Water resistance listed as 200M/20Bar. The US tables mark that rating for scuba diving. The Canada tables mark swimming, marine sports and scuba diving. Citizen’s US product copy also calls all three ISO-certified. Citizen Canada calls the two 40.6 mm models ISO compliant.
- Functions listed as 3 hand with date on every table.
- Cases listed as silver-tone stainless steel, with a unidirectional bezel on the US product copy.
Eco-Drive is Citizen’s light powered system. The E118 caliber stores energy from sunlight or indoor light, so the case stays closed for the usual battery change cycle that a dive watch would otherwise need. Keep the watch in the light if you want the cell topped up.
Citizen’s pages do not publish case thickness, lug width, weight or a numeric power reserve for these references.
The 44 mm Strap Model BN0251-04L
The BN0251-04L is the largest watch in the trio. Citizen lists a 44 mm case width, a light blue dial and a blue polyurethane strap with a buckle. The US page also describes the strap as navy blue. Citizen Canada’s page places the crown and the date window at 4 o’clock, and it describes a sunray light blue dial with oversized hands, applied markers and luminous accents.
This is the one to look at if you want the bigger case and a strap instead of a steel bracelet. Citizen US listed it at $425.00 at the time of writing.
The 40.6 mm Blue Bracelet BN0276-54L
The BN0276-54L shares a 40.6 mm steel case with the black dial model below. Citizen lists a blue dial, a stainless steel bracelet and a safety fold over clasp with push buttons. The US page describes a gradient blue dial with an orange seconds hand. Citizen Canada describes a sunray blue dial, a blue unidirectional bezel, a triple-link bracelet and a date window at 3 o’clock.
Citizen US listed this reference at $450.00 at the time of writing.
The 40.6 mm Black Dial BN0270-51E
The BN0270-51E uses the same 40.6 mm steel case, bracelet and clasp as the BN0276-54L. Citizen lists a black dial. The US page describes a black sunray dial with an orange bezel. Citizen Canada calls that bezel a bright orange unidirectional bezel and places the date window at 3 o’clock, with applied markers and lume on the dial.
Citizen US listed this reference at $450.00 at the time of writing.
How They Sit Next To Earlier Promaster Reviews
These new references sit in the same Promaster Dive family as two watches we have already covered, with different movements, crystals and case sizes.
The Citizen Promaster Sea BN0191 is an Eco-Drive diver in a 45 mm steel case with a mineral crystal and a steel bracelet. It is the regular solar Promaster we reviewed this week, running on caliber E168.
The Citizen Promaster Dive Automatic NY0129 is the mechanical option, with Citizen caliber 8204 in a 41 mm case and a mineral crystal on the blue strap version we covered.
The Uncharted Waters trio uses Eco-Drive and sapphire, and Citizen names it as a limited edition with Peter Miller. The strap model is 44 mm. The two bracelet models are 40.6 mm. If you already liked the BN0191 and want a solar Promaster with sapphire, these are the new references to compare on Citizen’s site.
Where To Find Them
Citizen’s US store lists all three as of this check.
Citizen Canada also has product pages for the same three references. I did not find Amazon US listings under these model numbers at the time of writing, so this post has no Amazon buy link. Recheck Amazon later if you prefer to buy there, and confirm the exact reference before you pay.
The Bottom Line
Citizen’s Promaster Dive Uncharted Waters limited editions are three Eco-Drive divers with sapphire crystals and 200 meter ratings, presented with Peter Miller. The BN0251-04L is the 44 mm light blue strap watch. The BN0276-54L is the 40.6 mm blue dial bracelet watch with an orange seconds hand. The BN0270-51E is the 40.6 mm black dial bracelet watch with an orange bezel. Citizen US had them at $425.00, $450.00 and $450.00 at the time of writing on 11 November 2026 at about 8.30am Manila.
