Hi there, I have a Speedmaster 105.012-66 HF. A beautiful watch! However, there's is one awkward thing and that is a missing Omega symbol on de bridge of the balance wheel (right beneath the place where adjustments to the speed can be made). The watch is in good condition and case, caseback, movement, dial and hands are true for the period wherin the watch was made. Does any one have experienced this or heard of a similar case? Thanks, Jeff.
