Comments about the data

Remarks
like ETA 2522, but Kif shock protection, different rotor shape, and anodized alumina barrel with life-time lubrication,
differences not known between 74, 624,
probably just the designators were changed in 1966, as samples with both numbers are known from this year

Example, year: signature; shock device
1966: HYL, Hamilton Watch Co. 623 (cal. 73 under balance), Swiss, 17 Jewels - Patented; Kif-Flector
(Hamilton 73)
