Addiesdive Tuna 300M Automatic Dive Watch AD2509

Owners widely praise the Addiesdive Tuna 300M Automatic Dive Watch AD2509 for its excellent value, with many finding the case finishing comparable to higher-priced brands and appreciating the sapphire crystal and strong lume. The Seiko NH35 movement is generally considered reliable and keeps good time, with some owners reporting accuracy within +1/+2 seconds per day, while others note figures around -6 seconds per day. The watch is seen as a competent homage, featuring a ceramic bezel insert and solid link bracelet. One owner noted the 39mm case size as easy to wear on a 7-inch wrist. However, some owners express skepticism regarding the actual water resistance beyond casual use, despite the 300m rating, and question the warranty's reliability. The bracelet is frequently described as significantly worse than that found on comparable brands, though still visually appealing. Quality control variance is a concern for some, with instances of misaligned bezel inserts reported.

Christopher Ward C60 #tide

Owners widely praise the Christopher Ward C60 #tide for its exceptional case finishing, which is considered unmatched on watches under $2,000, and its super bright lume, with one owner noting it is the brand's only model with a luminous dial. The watch is also lauded for its captivating blue-on-blue aesthetic, translucent wave dial, and the compelling story behind its construction from ocean-recovered plastic. Some owners question the ultimate purpose of the #tide's recycled material aspect, viewing it as potentially gimmicky, while others appreciate the conservation narrative and the bracelet's origin. The crown action is noted for its satisfying clicks. Overall, owners rate the Christopher Ward C60 #tide highly for its outstanding value and unique eco-conscious story.
