I have received the Royal Oak Panda Chronograph watch. I am very happy with it. It looks and feels very good quality. It's even prettier when you receive it than in the photos. I will buy it again.
I've bought two watches from this brand. The contact with them has been direct from the beginning, and they have more than met my expectations. I will definitely buy from them again.

Frequently Asked Questions
WHAT IS A SEIKO MOD WATCH?

What makes Seiko watches particularly amenable to modification is the widespread availability of replacement parts. This abundance of components allows for a wide range of customization, making each Seiko MOD watch unique .
WHAT MOVEMENTS DO WE USE?
We use Seiko automatic movements, which are famous for their reliability, precision, and long-lasting performance.
Movements we use in Crown Mods:
- Automatic movements NH35, NH36, NH38.
