What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

CIGA Design SKELETON

Owners widely praise the CIGA Design SKELETON for its value and willingness to challenge established brands, with some surprised by its quality. One owner reports their CIGA Design Series Z in Black DLC has been perfect for over four years, keeping good time and looking neat. However, some find the skeletonized movement's visibility obscured by reflections due to the lack of anti-reflective coating on the crystal. One owner reported their CIGA Design Z Series Skeleton broke after three months with no customer service response. Overall, owners rate the CIGA Design SKELETON highly for its surprising quality and value proposition.

Seiko Prospex Sea

Seiko Prospex Sea models are widely praised for their excellent build quality, value for money, and comfortable wearability, with many appreciating the vintage-inspired designs and robust construction. Owners note the silicone straps are surprisingly comfortable and well-finished, and the Lumibrite lume is excellent. However, some find the 44.3mm size and thickness too large for smaller wrists, though others report the sizing as perfect. The 6R15 movement in some variants offers accuracy around +4 seconds per day with a 50-hour power reserve, while newer movements offer more. Some models are criticized for a bracelet width not matching the case size or a rudimentary clasp for their price point. Overall, owners and reviewers rate the Seiko Prospex Sea highly for its impressive case work and finishing at its price point.
