Case/Model Specific Watch Strap

I'm looking for a nice OEM leather watch strap for my 38mm Aqua Terra. They have some nice ones on the Omega website but none of them are formfitting to the Aqua Terra case. It seems like all of them leave a gap between the case and the strap (picture attached). My question is, where can I find an OEM leather strap that is made specifically to form up with the case of the 38mm Aqua Terra (ref. 220.10.38.20.03.001) and not leave a gap?

Looks like it came with one fitted strap:

You'd need to go to an Omega boutique or authorized dealer and ask them to oder this strap for you. Note the buckle is sold separately.

FYI, the strap shown at the link i above s a rubber strap, not leather, and I understand you have to order the metal inserts separately as they're not included in the strap

I came across this guys video on YouTube where he had an OEM black alligator strap for his Speedmaster (link posted below). The strap reference number is 98000349. I'm looking for something like that, except for an AT.

I can't vouch for either of these personally, but I've rave reviews of both; people seem really happy with their work. These may be a good alternative when a curved spring bar leather strap was not offered from the factory:
