Ever since its first diver’s watch in 1965, Seiko has developed new technologies, features and designs that have made the Seiko Prospex diver’s watch collection a favorite among professional and recreational divers the world over. Through more than a half-century of innovation, Seiko has continuously pushed back the boundaries of where sports watches, and diver’s watches in particular, can go and how they can be used. Continuous enhancements over the decades in safety, reliability, legibility, and ease of use have made Seiko a leader in diver’s watches.

Seiko is introducing a new movement in the long-trusted 6R family that has a GMT function and a power reserve extended to a full 72 hours. Caliber 6R54 is presented in three new Prospex creations that are all modern re-interpretations of a Seiko classic from 1968 and are designed for diving with 200-meter water resistance.

This is definitely the Best modified seiko watch service/Company that you can ever encounter. From the day I start enquiry and converse with the staff in regards to the watch I want to mod for only took few hours to confirm and they can immediately initiate the watch parts orders from overseas to mod parts that I wish for. Staff was polite, responsive shown absolute professionalism and offer several other colour or parts from the watch to offer me more variety of choices to make. Couldn't be anymore satisfied. Great Job Customwatch Haven ! Very good purchasing experience indeed!

Recently bought a new Seiko watch from Customwatch Haven and I couldn't be happier. They had the exact model I was looking for at a competitive price. The staff was friendly and patient, explaining all the features and answering my questions thoroughly. They even helped me adjust the bracelet for a perfect fit. Overall, a great experience and I'll definitely be back for any future watch needs or mod projects.

Customwatch Haven is a watch lover's paradise! They have a massive selection of Seiko and Casio watches, both classic and modern styles. But what truly sets them apart is their extensive collection of mod parts. I was able to completely customize my Casio G-Shock with new colors and functionalities, thanks to their expert advice and wide range of options. They even have pre-modded watches that are absolute eye-catchers. If you're looking for a unique timepiece or want to unleash your inner watchmaker, Customwatch Haven is the place to be!
