My first modded watch, and dealing with Chin made the entire experience seamless. He’s incredibly knowledgeable and genuinely willing to share his expertise. As for the watch itself, the build is impressive, utilising high-quality parts that feel truly premium on the wrist. If you’re in the market for a custom watch that looks and feels top-tier, you absolutely have to check him out.
Very pleasant experience. Seller went the extra mile to resize the watch for my tiny wrists and explained how to use the watch clearly. 10/10 would recommend !
Bought many watches, vintage and mods alike from Chin many times already. Mods workmanship is solid, and Chin is obviously someone who takes great pride and care in his craft. Highly recommended!
Watch looks good! Very informative and helpful. Willing to answer any doubts or questions that you may have.
