An essential time-only from the Citizen OF collection
The Citizen OF BM8550-81A is a timepiece with a sober, masculine character, designed for those seeking a versatile watch to wear every day. The readout is immediate thanks to the day date function integrated into the dial, while the 41 mm case ensures a balanced presence on the wrist, suited both to the office and to leisure.
Eco-Drive technology: the power of light
At the heart of this watch is the Eco-Drive movement, Citizen's exclusive technology that turns any source of light, natural or artificial, into energy. It requires no battery replacement and, once charged, offers a power reserve of up to 180 days, continuing to run even in the dark. A reliable, clean movement that combines precision with respect for the environment.
Construction, materials and the Oreficeria Ravelli warranty
The case is made of 316L stainless steel with a screw-down back and protected by scratch-resistant mineral crystal. The 10 bar water resistance makes it suitable for everyday use and occasional contact with water. Every Citizen purchased from Oreficeria Ravelli, official retailer, is covered by the official 2-year Citizen warranty, extendable by a further 3 years (up to 5 years in total in Italy; abroad, the 2-year warranty applies); our in-house workshop is on hand for advice and assistance with your watch.
