Comments about the data

setting handle at the bottom
4 Kif-Duofix combined settings
The hack feature is realized with an extended setting-wheel spring, blocking the fork. So a 214 can be easily converted to a 214H. But it is not worth while: The watch doesn't start immediately after flipping down the handle, because the fork needs some time to restart oscillating.

nickel plated, up to 1968 / gilt since 1968:
214/2140: base
214H/2141: hack feature
214HN/2142: hack feature, second time zone
-/2143: since 1970, features unknown

Example, year: signature; shock device
1962: M2, Bulova, U.S.A., Pat.2.971.323
(Bulova 214)
