Omega Seamaster Aqua Terra 150m 19mm Springbar Part Numbers

Greetings folks

I recently bought a nice condition Omega Seamaster Aqua Terra 150m in quartz. It is model 231.10.39.60.06.001

I have had the watch band adjusted several times by the place I bought it from, before crying Uncle and giving up on the metal band. it is ether a bit too tight or a bit too loose. I tried a combination of 2 half links with a full link removed and removing the 2 half links and adding the full link back. Nothing worked. I am not a bracelet person anyway so I i removed the band and banished it to the red Omega box. I currently have it on a 20mm strap with some older 19mm spring bars.

I found out that Omega uses the same principal that most other watch companies do. They use a smaller spring bar for the bracelet version then the strap version to put the bracelet on quicker in the factory. The spring bar that came with the watch is too small for use with a strap.

Does anybody have the part number for the 19mm spring bar that goes on the Omega Seamaster Aqua Terra 150m with the 19mm strap? or a part number for general Omega 19mm spring bars?

Thanks

Sorry, I'd love to help with the #, but my suggestion would be to either visit, or if too far to drive, call an OB, I'll be willing to bet they'll be able to help.
