Let customers speak for us
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.
Bought the case. It is really a unique product that doesn't exist anywhere else in the market. For anyone who likes Royal Oak and like a smaller footprint, this is an unmissable offering. Thank you Nomods.
Everything was perfect. Shipping was fast and the product is of very good quality. In my opinion this is a the best Royal Oak mod you'll find on internet
Absolutely love the watch, it look realy good and adjusting the band was really easy
Awesome watch! Excellent piece from these guys. This is the 3rd piece and I have never been let down:
Really well made, very happy with the product.
Very highly quality RO homage case. 37mm is a perfect fit for smaller wrists.
This is the perfect size for this style of case. The quality of the cases is top-notch, they feel and look excellent. Additionally, Mathias from Nomods is also very friendly and professional and helped me out with all my questions and customization requests.
Perfect size, perfect size case with the bezel being the right size. It is not too thick or too narrow, it is just right
Very nice case and very good quality
