What people say

Owners + reviewers, side by side

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

Furlan Marri Disco Onyx Diamonds

The Furlan Marri Disco Onyx Diamonds is lauded for its striking black onyx dial, elegant lab-grown baguette diamond hour markers, and art deco design. Owners and reviewers highlight the watch's beautiful appearance and vintage charm, noting its comfortable 38mm case with hidden lugs and a slim 8.95mm profile. The manual-winding Peseux 7001 movement, decorated and considered a good fit for the slim case, is also a point of praise. However, some find the CHF 3,500 price steep for a microbrand watch with an off-the-shelf movement and case, with one owner noting this diamond-embellished version is significantly more expensive than other Furlan Marri models. The design is also noted by one source as potentially reminiscent of other brands. Overall, owners and reviewers rate the Furlan Marri Disco Onyx Diamonds highly for its luxurious dial and diamond indices, despite some reservations about its price and movement origin.

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.
