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
Nice seller
I am creating a custom watch build for my brother who works at a gym. I wanted something equal parts sport and elegance and the Petrichor meets and exceeds my standards for both. Really solid build quality with exceptional finishing, and a comfortable micro-adjustable bracelet to boot. I will be buying from NoMods again.
Fantastic quality. Looks exactly like the image. Looks great.
