Watch Crystal Lens Glass 15~41.5mm Dia. Sapphire Mirror Round Flat Replacement Parts for Watchmaker Repair

The product was excellent quality sadly a bit too small for my watch as I measured wrong.

Perfect and permanent replacement for round glass crystal.

presentation seemed to be an assortment of crystals of different sizes, but was not. It turned out to be a single crystal not close to the size i needed. On closer inspection that is what it said, but it was certainly not clear and the picture seems to suggest otherwise.

Quality as expected, high.

I was mislead into believing the package would contain several units rather than just one of the crystals.Very disappointing after having paid a similar price from another source and receiving a dozen units from them.

The product is great, but the add is misleading. I was expecting to receive an assortment of lenses as shown.

I bought these to replace the mineral crystal on some of my Seiko 5 watches. Unfortunately it took a bit for me to figure out how to install these without shattering them, but it was my fault, not a fault in the product. Once I learned how to do it I was able to get them installed and my watch collection looks great.
