Excellent quality, great upgrade and fit, highly recommend.

Great crystal. AR coating works wonders and no milky ring at all. Will be purchasing many more!

Bought a DJ41 white gold-plated fluted bezel and a gasket. The gasket broke upon attempted installation. Emailed David and he quickly provided another which worked perfectly. Love them both! Great Service!

Excellent clarity. Really makes my Daytona dial pop

Have bought dozens of deep crystals and can confidently say this is a must do upgrade especially with black or colorful dials. Highly recommend, super quick shipping and excellent customer service, will buy again. Also bezels are an excellent upgrade as well

Thank you deep crystal for the awesome AR and black hole effect! Fast reply and fast shipment. Thank you again!

Selection was very clear and easy to understand. The entire process was very smooth and fast shipping was acceptably fast.. The watch crisp is very nice. Definitely makes a great improvement on any watch. I think it's even improvement over some of the OE crystals definitely worth the investment..

As always, the crystal are great and service are always top notch. Thank you, Deep Crystal!

Muito rapido e cristal de primeira. Comprei do Brasil e chegou em 11 dias
