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 owners and reviewers praise its Marinemaster-style aesthetic, excellent case finishing, and impressive LumiBrite lume. The watch is powered by the 6R15 movement with a 50-hour power reserve and comes with both a steel bracelet and a silicone strap. Some owners find the Seiko Prospex Sea to be a great value and a suitable first "proper" watch, while others report it is uncomfortably big, thick, and heavy on smaller wrists. Reviewers note the GMT function is secondary with a less prominent scale, and the bezel's quieter clicks may not appeal to all. On balance, owners and reviewers rate the Seiko Prospex Sea highly for its classic design and finishing at its price point.
