Furlan Marri Disco Onyx DiamondsvsGrand Seiko SLGH005

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.

The Grand Seiko SLGH005 is widely praised for its stunning "White Birch" textured dial, exceptional finishing including mirror-polished indexes and Zaratsu polishing, and the innovative Caliber 9SA5 movement. Owners and reviewers consistently highlight the dial's texture and the elaborate, mirror-like indexes. The watch's 40mm stainless steel case is noted for its slender, sporty design and comfortable wearability, with some finding its size well-proportioned and its brushed and polished surfaces practical for hiding scratches. The 9SA5 movement is recognized for its 80-hour power reserve and 36,000 vph hi-beat frequency, though one owner found its finishing less impressive than other movement types in a similar price bracket. Some reviewers consider its price somewhat high relative to alternatives and desire a micro-adjustable bracelet. On balance, owners and reviewers rate the Grand Seiko SLGH005 highly for its exquisite dial and finishing, powered by an advanced high-beat movement.
