Using this mod part for: LA Seikonaut
Best quality

This review is for the parts I purchased for a new build. I got the rotor, movement, hands and the Seikonaut kit. Everything about the parts I purchased was first class. Hands down the best quality I have seen in almost 3 years of modding, The packaging was unique and the shipping was FAST, 5 days from Singapore to my door in Wyoming, USA. The design of the case was well thought out and perfectly executed. The total time for the build was under one hour (I'm fairly well versed in watch modding), and the finished product is beautiful. The most surprising part of the kit was the solid end links that **** in just like the links. That was something I was not expecting and it made attaching the bracelet simple and quick. Kudos for that. Many thanks for the total experience.
