Citizen Corso Diamond

Ref. BM7644
Dress

The Citizen Corso Diamond is widely praised for its attractive dial, with owners highlighting its sunburst silver or blue finishes and light-catching qualities. Its reliable Eco-Drive movement, offering solar-powered, maintenance-free operation, is a significant draw, as is its value proposition compared to higher-end brands. Owners also appreciate the sapphire crystal for its scratch resistance and the watch's overall sturdy, well-built feel. Some find the 41mm case size and 44-46mm lug-to-lug comfortable for daily wear, noting a 70s statement feel or Genta-inspired look, while others consider it too large or awkward on smaller wrists. Mixed opinions exist regarding the polished case finish, with some finding it too shiny and others praising its immaculate finishing. The band's lining has been described as unpleasant by some, and one owner noted inconsistent seconds hand alignment and a small date window.
