What people say

Owners + reviewers, side by side

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

Oris Big Crown Diamonds

Owners widely praise the Oris Big Crown Diamonds for its timeless design, vintage charm, and recognizable details like cathedral hands and the pointer date function. Reviewers highlight the stunning gradient dial and the "Bullseye" tuxedo dial as particularly beautiful. The 38mm case is considered versatile, and the watch offers remarkable value. However, some owners note the standard Sellita movement has a short power reserve and plain finishing, and the strap is not durable. A reviewer points out slightly imperfect Super-LumiNova printing on the hour numerals, and one owner finds the two-tone bracelet overly flashy. On balance, owners and reviewers rate the Oris Big Crown Diamonds highly for its unique design and value at its price point.

Phoibos Reef Master

Owners widely praise the Phoibos Reef Master for its exceptional value, highlighting its sapphire crystal, DLC coating, and extensive BGW9 lume. The watch is noted for its cool lume, with one owner finding it not bulky despite its robust build. The Shamrock Green dial and texture are highly praised, as is the comfortable bracelet with solid end links. However, the bezel action is described as rough, and the basic folding clasp is a disappointment. Accuracy is reported as excellent, with one owner seeing +-2 sec/day. Some find the 42mm size almost too big for their wrists, and the date window is considered too small. Overall, owners rate the Phoibos Reef Master highly for its impressive feature set and value at its price point.
