Within the set of Heuer Autavia 3646 1st execution dial and 2nd execution hands pieces seen, the crown is primarily unsigned dome (see below). We do see a few pieces with signed crowns featuring the Heuer logo, but given nearly all are unsigned, I believe the signed crowns are either replacements or otherwise not intended as the crown originally designed for this set of Autavia 3646.
Round pushers are found on the 3646, with pusher diameter of [TBD], height [TBD] and tube diameter of TBD].
