Seiko Brightz
1. Any info about the 4s20 caliber? Are they still using this in any watches?
2. Is the antifreflective coating only on the inside of the crystal or on both sides?
Any other info about the piece would be great!
Thanks!!!
Answer:
As far as I know the anti-reflective coating is just outside. I found some old pictures showing a Seiko Credor with the 4S27 from 2002. May also refer to the 4S20.
