The Super Compressor lid?

[Hugger69]

Hi folks,
Does anybody know exactly how the lid of an Enicar Super Compressor case should look like?
Mine looks like below and doesn't have a spring ring on the inside, is that correct or is that a part that I miss?

The lid looks right. There is no part missing

Thanks!
But here is another lid with a spring from a watch buddy and it´s also an Enicar watch:

Not all super-compressor case backs have a spring:

One moment, please...

 

[Hugger69]

Yes, I know of that site but I wanted to hear from you guys why and which watches differs?

Interestingly I was thinking about this recently Hakan. I have 5 Sherpa Graphs and a new one arrived a few weeks back that had this exact spring in it. None of the others did at all. Very strange. Whether they were just removed at service or not, I have no idea? What function do they actually perform though? Does it help to pop the caseback off once you've loosened it?

Interesting to hear Steve!
Didnt know that the Graphs had Super Compressor cases too?

*EDIT*

All Graph cases used a super compressor EPSA case. I doubted myself for a second there!

 

[HorologyBiology]

Most I’ve owned have been without.

The Jet Graph I picked up recently was in amazing condition and did contain one. I think they more than likely all came with them but just got misplaced during a service maybe?

I think they do serve a purpose though by adding a little extra tension on the caseback, other wise why have it in the first place.

I haven’t taken my NOS Sherpa Guide apart yet but that would be interesting to check out...

But if you read about the Super Compressors, all of them didn’t have that spring in the lid so that’s why I started this thread...to get som light on the mysterious spring and when it really was meant to be?

 

[HorologyBiology]

Or maybe it’s the other way around and that some watchmakers added them ‘thinking’ they were missing

That’s a thought too....
But could the spring in my buddy’s picture above be the same as in this sketch under SUPER COMPRESSOR below:

These Enicar bayonet cases are EPSA cases. But are they EPSA Super-Compressor cases?

EPSA Super-Compressor signed cases carry the Brevet (patent) numbers: 317537 and 337462.
The bayonet mount Enicar cases carry a different Brevet number: 314962 (and aren't stamped
'Super-Compressor' inside as far as I know).

The Brevet 317527/337462 EPSA Super-Compressor cases have a spring.
Whether or not the Enicar EPSA Brevet 314962 cases should have a spring I don't know.

From The Spring Bar:-

All Graph watches used the Super Compressor bayonet case made by case manufacturer Ervin Piquerez S.A. (EPSA) exclusively for Enicar. This was subject to brevet or patent #314962. This can be seen engraved on the back of the case, and stamped inside the case back is a diving helmet. The Super Compressor cases also have a cross hatched crown.

Enicar Graph Collector's Guide

INTRODUCTION A separate article has documented the development of the Sherpa brand which you can read here, and the further development of various models of 36mm to 40mm diameter, single and two crown, pilot and dive watches. This article covers the 3 crown Enicar Sherpa Graph chronometer...

Whether that is correct, I'm sure @JimJupiter can confirm!

It's not correct in that there is no diving helmet stamp inside the casebacks.

Great to hear Steve!
....but the main question still remains to be answered...which lids did get the spring and why?

 

[Hugger69]

Just looked a bit closer on the insida of the lid of my Sherpa Date and it do have that spring too!
If you look closer you can clearly see that spring....

Interesting discussion regarding Compressor or Super Compressor or something else. I just talked to a guy who was in the EPSA archives and in my opinion is the only one who could know. Technically he says, the Enicar watches are no Compressor nor Super Compressors. If I understand him right, the bayonett caseback doesn't fit in any of the classical EPSA classification...but its closer to the SC specification.

Regarding the spring. Good question, I thinkt they should be in any caseback and I guess they were just lost in time.

Any NOS examples here that were never opened?

Wow, so you mean when we all talk about Enicar Super Compressors we´re actually lying?
When you read about Enicar, EPSA and Super Compressor that´s almost like one uniformed object so this info really put things in another light!

 

[JimJupiter]

Well,...lets see it that way. It's as good as a Super Compressor but with the super cool (and maybe even better) bajonet caseback. He said, if you be precise, you would need to find another name for that kind of case design I mean as yourself find out, ...the brevet numbers are unique to Enicar and differ to the SC brevet number.

That´s a much better way to put it!
