Fireman_Fred Posted April 5, 2011 Report Posted April 5, 2011 Does anyone know if the crsytals from an ETA SMP and A7750 SMP Chrono are the same and can they be interchanged?
ryaku Posted April 6, 2011 Report Posted April 6, 2011 As far as I know they have the same measures. SMP chrono sapphire (rep crystal) I have in my box is Diameter 30.42 mm Thickness 2.21mm close the edge (thicker in the middle) Hope it helps
