Furlan Marri Disco Onyx DiamondsvsGrand Seiko SLGA009

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 SLGA009 "White Birch II" is praised for its Spring Drive Caliber 9RA2 movement, offering exceptional accuracy of ±0.5 seconds per day and a 120-hour power reserve. Reviewers highlight its refined dial texture, inspired by Shinshu forests, and the Series 9 design with a frost-finished movement. The watch features a 40mm stainless steel case and a power reserve indicator on the movement bridge. However, its price of $8,600 to $9,100 USD is noted as relatively expensive, reflecting Grand Seiko's increasing price points. Overall, reviewers consider the Grand Seiko SLGA009 a highly refined timepiece, with its advanced Spring Drive movement and aesthetic improvements being key strengths.
