Need 371 battery retainer spring

[Smokey]

Cannot seem to find a battery retainer spring for the 371 battery in a Ronda F07-111. Esslinger sells a bundle of battery retainers, but this part is not included. Any help appreciated.

Looking on this site it doesn't need one.

I believe the retainer may be part of the case assembly, but was hoping it was available separately.  This is a Marathon JSAR military issue designed for high impact.

Photo is of the exact watch with retainer.
