Tired of the Hardlex mineral crystal on your Seiko Sumo?
Now you can purchase a soft domed sapphire with AR coating underneath with us.
So what happens when you purchase this option with your new Seiko Sumo?
1. We switch out the sapphire crystal with our compatible Sumo soft domed sapphire crystal with anti-reflective coating on the inside.
2. A waterproof test will be done thereafter to ensure that it maintains the factory water resistance ratings.
3. For an added peace of mind, we will include the waterproof certification as well.
Disclaimer:
If the Sumo is purchased from Gnomon Watches, the watch will still have the full 1 year Gnomon's warranty from the date of purchase.
For all these to be done, we will need additional 2 working days for our watchmaker to complete.
The soft domed sapphire crystal is applicable only to the following models:
Prospex 200M Automatic Black Sumo Ref. SBDC031
Prospex 200M Automatic Blue Sumo Ref. SBDC033
