Citizen Promaster Uncharted Waters dive watches, Digi Mart USA News (United States): Citizen has officially launched three new watches from its Promaster Uncharted Waters dive lineup in the US market, following a launch in Canada last month, according to a Notebookcheck report published November 11, 2026.
The three models are the BN0251-04L, the BN0276-54L and the BN0270-51E. The report says they differ mainly in cosmetic design, while their hardware and specifications remain largely the same.
The BN0251-04L has a 44 mm case, a light blue sunray dial, a silver-tone bezel and a blue polyurethane strap, with the crown positioned at four o’clock. The BN0276-54L and BN0270-51E have a slightly smaller 40.6 mm stainless steel case paired with a triple-link steel bracelet featuring a safety fold-over clasp and push-button release.
The BN0276-54L has a blue sunray dial with a blue unidirectional bezel, while the BN0270-51E has a black dial with an orange bezel.
Inside, the watches use the Caliber E118 Eco-Drive movement, which the report says was introduced earlier this year. The solar-powered movement can be charged by any indoor or outdoor light source.
The watches are described as ISO-certified for scuba diving and rated for 20 bar (200 m) water resistance.
All three share minimalist dials with hour markers, three hands and a date window, and sapphire crystal that the report says helps protect against accidental falls and scratches. The publisher lists the BN0251-04L at $425 and the BN0276-54L and BN0270-51E at $450 each.
Buyers can purchase them directly from Citizen’s US website.
