Unimatic's minimalist design principles find their highest expression in the Serie 8 U4S-8B. The diver-inspired watch sports a black dial with cream indices and a minute track in burnished gold. While the 40mm stainless steel case doesn't have the rotating bezel found on diver's watches, the screw-down 8mm crown and back do offer water resistance of up to 300m. The Sellita SW200-1b movement incorporates a hacking seconds hand and provides a power reserve of 41 hours. A black strap, NATO seatbelt strap, and Unimatic Unimatic Tough case that can store two watches are included.
