2500 A, B, and C

In Response To: Relationship of 2500 to Caliber 2628 ()

: Got it, thanks John. How do the 2500A, 2500B
: and 2500C fit into the picture? Geo

I don't recall the details of version A, but Omega modified the beat rate and lift angle slightly when they switched from the B to the C version.

2500B has a beat rate of 28,800 beats per hour and a lift angle of 30 degrees. 2500C has a beat rate of 25,200 beats per hour and a lift angle of 38 degrees.

George Daniels, the founder of the co-axial escapement, recommended the lower beat rate for optimal efficiency, so hopefully Omega will now stop at version C. Version C is now used in all new Aqua Terras and has been used in the Planet Ocean from day one. Versions A and B are no longer in production.
