Please have a look to this.
I can agree my cap is thinner, but also tube size in my Compur is similar to SALA than in Highlifewatches compur.
I found some others on internet, and I can not precisely say which is correct, but highlife is the similar I could found.
Also when one size and crop the picture the ration between large and high changes and that might have some influence.
Any way watch is now at SPA, and to my watchmaker tubes are correct, and caps fitted perfectly to him, but who knows.
I am pleased with the watch, and in the end that麓s what matters to me.
Thanks for all your feedback

No prototypes for sure, but rare I think so
