Citizen Series8 Automatic 40.8 mm Grey Dial Two-Tone Stainless Steel Bracelet [NA1034-51H]

The Citizen Series 8 870 Automatic [NA1034-51H] blends refined design with advanced mechanical precision. Its 40.8 mm silver-tone stainless steel case with two-tone bezel frames a grey textured dial under anti-reflective sapphire crystal, offering excellent legibility with rose gold-tone applied indices and lume-filled hands. A practical date window at 3 o’clock enhances daily functionality, while the integrated bracelet’s polished and brushed surfaces create a sleek, cohesive aesthetic. 

Powered by Citizen’s in-house Calibre 0950 automatic movement, this Series 8 model delivers reliable timekeeping with a frequency of 28,800 vph and an approximate 50-hour power reserve. The movement also features magnetic resistance and can be viewed through a sapphire exhibition case back — a hallmark of engineering transparency in the 870 lineup. 

Designed for everyday wear, it offers 100 metres / 10 bar water resistance, making it suitable for swimming and light water activities while retaining a refined sport-driven style. The tapered two-tone stainless steel bracelet with hidden push-button clasp ensures a comfortable and secure fit on the wrist, embodying Citizen’s commitment to both form and function.
