crystal number

Can anyone help me with the number for a 26 Conquer. GS or BB or Federal.

Hi John. I don't have a 1926 Conqueror to measure, but the 1952 G-S catalog lists a square crystal with cut corners measuring 21.5 X 21.5 as being for a Bulova. The number for that one is G-S Q380.

Lisa has a watch labeled as a 1926 Conqueror and lists the crystal dimensions as 21.0 X 21.0. The only one G-S lists with those dimensions is the G-S Q360, but it's labeled for a Waltham. But you can't always go by the brand name G-S lists. They did make mistakes.

I've used the 21.0 x 21.0 before with success. They do require a small amount of grinding but that is mainly to decrease the depth of the side walls.

I don't think we have ever established the correct original crystal for the LE/Conqueror.
