Monza strap

Hi?
Would anyone be able to help me find out what strap was fitted to my Monza black coated 150.501?
I bought it with a solid black leather one but suspect it originally had a rally version but photos are confusing.

Many thanks

We have a few catalogues that feature the Monza- you can see them here:

I've seen two different strap design- one the standard corfam straps and the second the large hole style that we saw on the 40th Anniversary TAG Heuer re-edition. I've never seen the second one for sale, so your best option is the corfam. I'd suggest contacting Abel Court at HeuerTime to see if he has any available.

Thanks very much
