Citizen has officially launched three new Promaster dive Uncharted Waters watches in the US. The lineup includes three models, namely, the BN0251-04L, the BN0276-54L, and the BN0270-51E. The former ships with a rubber strap, while the latter two are paired with stainless steel bracelets. All three models feature the Caliber E118 Eco-Drive movement and 200 m of water resistance. 

Following the Canada launch last month, Citizen has now officially launched its latest Promaster dive Uncharted Waters watches in the US market. The company has unveiled three new watches under the Promaster lineup, including the BN0251-04L, the BN0276-54L, and the BN0270-51E. All three models differ primarily in their cosmetic design, while their hardware and specifications remain largely the same. 

Speaking more precisely, the BN0251-04L features a 44 mm case complemented by a light blue sunray dial, a silver-tone bezel, a blue polyurethane strap, and a crown positioned at four o’clock. The Citizen Promaster BN0276-54L and the BN0270-51E come with a slightly compact 40.6 mm stainless steel case paired with a triple-link steel bracelet with a safety fold-over clasp and push-button release. The former features a blue sunray dial with a blue unidirectional bezel, while the latter gets a black dial with a catchy orange bezel. 

Inside, the Promaster dive Uncharted Waters watches have a Caliber E118 Eco-Drive movement, which was introduced earlier this year. This makes them solar-powered watches, which can be charged using any indoor or outdoor light source. These watches are ISO-certified for scuba diving and rated for 20 bar (200 m) water resistance. 

All three watches have minimalist dial elements, featuring hour markers, three hands, and a date window. Furthermore, there’s sapphire crystal on top, protecting these dive watches from accidental falls and scratches. As for price, the BN0251-04L starts at $425, while the BN0276-54L and the BN0270-51E are priced at $450 each. Interested buyers can now purchase the new Promaster dive Uncharted Waters watches directly from Citizen US’ official website.
