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.
