Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners find the Citizen Promaster Sikorsky's dial "amazingly busy" and angular, a characteristic some find amusing while others deem it solid. This 46mm solar-powered watch features atomic time syncing, a slide rule bezel, and a red, white, and blue dial with yellow accents, honoring the S-92 helicopter. On balance, owners appreciate the unique design and functionality, despite the dial's complexity.
The Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited Edition is praised for its retro design, balanced 42mm case, good finishing, and sapphire crystal. It is powered by the calibre 8R48, featuring a column wheel and vertical clutch, and offers 100m water resistance. Some find its 45-hour power reserve short compared to modern alternatives, and the date window placement is a point of discussion. The solar-powered variant is noted for its compact proportions and character, though some desire thinner cases and improved bracelet micro-adjustment. Overall, owners and reviewers appreciate the SPEEDTIMER's vintage-inspired aesthetics and solid build, with critiques focusing on power reserve and minor functional details.
