Can be very time consuming (a few hours) if you are particular about how perfectly aligned your film application is, but well worth it.
The cutouts are 99% of the way there, with some rounded corners to prevent lifting. Some bracelet films may seem a bit short, perhaps by design to allow for more flexibility.
The bezel is easily the most difficult section to put on because the surface is conical rather than flat. It requires a lot of micro adjustments and holding in place as the water dries out and the film stretches into place. Requires some effort to get it appearing flawlessly.
More water leads to a cleaner application but longer drying time. Use more water on the crystal and polished surfaces to avoid specks and dust.
I can wear my watch confidently knowing that it's protected and without checking obsessively for scratches. Shipping was very fast. Much appreciated.
