Hi Dan,
that pusher head is closed to the original but it isn't
the right one and I don't think you can screw in on your
pusher.
Probably you will find in ebay one complete pusher but
it seems very expensive.
Anyway, for what I know the right diameter is 4.4mm.
Hope this help, good luck.

: Hi Guys

: I woke this morning after a night out to find that my Vintage Heuer
: Monaco 1133B lost one of the pusher heads (the one at 2
: o'clock). It now looks like this previously posted pic:

: I have searched the trader site but can only find people wanting to
: buy pushers for a Monaco, not anyone offering a pusher for sale.
: Turning to ebay, I have found this:

: The head appears to match what I need (with the measurements of the
: head seemingly matching the one I still have left on my Monaco).

: Could this ebay item work (i.e. could I unscrew the head and use it
: on my Monaco)?

: Can anyone help me to source a replacement pusher head?

: Thanks in advance
