I finished this one just in time for Christmas. It's a gift for my son-on-law. The quality of the case and bracelet are outstanding. The build went smoothly with no fitment problems. Removing the pins to resize the bracelet was easy with no issues at all. I like this one so much, I may have to build another for myself!
Beautiful case.
This was one of the only 37mm RO mod cases I could find, and I’m glad I went for it. The price is slightly more premium, but you get great quality in return. It has good weight, and the dimensions are great. While not a 1:1 to the real thing, it definitely does a good job of paying homage to the RO.
It was also packaged and protected very well, and so it came in perfect condition. Shipping time was good but do understand that it is dependent on where you live.
This has made me a fan of the brand, and I will definitely keep a lookout for more case iterations and new products in the future.
good quality machining , the watch looks great, no complaints
It is a masterpiece!
Thanks a lot it is amazing!
This dial compliments my 37mm Seikoak beautifully along with the rose gold hands. The fit was perfect and the gunmetal watch is one of my favorites.
Unexpectedly great and precise workmanship! I'm ordering more!
As advertised and expected. Genuine TMI part.
Beautiful case and bracelet. All parts fit well, the only issue came when resizing the bracelet. I should have read through the website first - I hadn't read the warning to wash the bracelet in warm soapy water first and I had a screw become stuck. It all worked out fine in the end, just a minor annoyance. The 37mm size fits my 7-3/8" wrist much better than I thought it would. I like it so much that I ordered a SeikoNaut case/bracelet which I'm currently waiting for.
The case is well made and polished. Extra screws are included which is appreciated.
Shipping was a little bit slower than I expected, but it happens.
Excellent quality workmanship on the entire watch. Bracelet is well polished and looks amazing!
Finishing on the case is 10/10, perfect for smaller wrists. I broke one of the pins when I was shortening bracelet but that was my fault (that was not a problem because there are enough links).
I had a few questions for the owner who responded very fast on my emails.
High quality case waiting for two 1.5 links to complete the fitting due to having a large wrist.
Perfect fit in my NH movement and petrichor case, thanks!
