FT6068 vs FT6069 Aquaracer rubber strap question

I have a 41mm Aquaracer and looking to add the oem rubber strap. However both the FT6068 & FT6069 appear to be the same size... What am I missing? I’ve read so much different info regarding the lug width on both the 41 and 43mm aquaracers. Some say the same, some different. Has anyone tried to fit the FT6069 to the 41mm case as I’ve found it for much cheaper than the Ft6068 on a couple websites. Thanks in advance.

The strap for the 41mm model is FT6068 with yellow lining- I believe this fits a 20mm lug

FT6069 is the same strap for the 43mm case, which I believe has a 21mm lug.

Given that it's a hard rubber, I doubt the larger strap would fit the smaller case.

Thanks for the info! Back to the drawing board.
