Bimetal nostalgia for WE, because too hot for a watch on the wrist .....

Thanks for the incredible photos Hebe

Adrian,

(alwaysiwc).

Lovely pictures and lighting!

What caliber is that? My pocket watch looks to have the same caliber, except
the fine adjustment balance lever(?) is different on facing the other way. I
think mine is a c95.

Good work, nice piece. Only few of the c.67 have the goose neck spring for the
setting.

It was the wok horse ("heavy" movement H5) of IWC, when the c.52 was stopped.

I assume the balance was taken out of an c.52 H5.

Kind regards

Interesting aspect Ralph.

Many refs. of that era have very similar or identical balances.

The "Fournitures" Book shows a cal. 67 with a bimetal balance.

But another NOS cal. 67 from 1942 has a Glucydur balance. So, both types of
balances have been used.

An another bimetal balance from that era. JLC base movement used by VC.

Hard to belive the balance is original...,

I never saw an original balance with added copper rings under the screws...

But you are rhgt, I have never remarked it, in the furniture catalog most of
the pocket watch movements are shown with com. balance.

But the balance looks differernt in one of my movements

Great shots of the IWC later workhorse PW movement c.67 (H5).

Recently I bought a watch with a somehow special c. 67.

Firstly it is wearing my initials R.E. (and making me some years younger ;-) )
and

Secondly it has a quality I never saw before: at least 17j, (I have not
removed the dial to check it ther is a jewel on the minutes wheel or a cover
jewel on the escape wheel too) and goos neck fine adjustment, not very common
on the c.67

To compare a place an "normal" work horse movement with compensating
(bimetalic) balance beside: 15j no goose neck fine adjustment:

herer some pictures of this pair:

I will work in better pictures, when I find time to set up my photo
equipment....

Yes, this is correct, many of them have goosneck fine adjustemns, but the
finish of the movement ist poor: no genava strips decoration, just 15 j.

Sorry bad picture old picture from 2002, I just found in my docs.

Thanks for the hint about the strange balance Ralph,

and for the effort as well.

I have two C.67 glucydur balances in stock, but the bimetal balance works
fine. So, no need to change it.

And a decorated C.67 BUND with goose neck adjustment.

Hi hebe et al,

really interesting that there are copper or even better gold washers under the
balance poising screws. It would be very interesting to know if that was done
by the factory. The addition of the washers increases the balance inertia.
However that is a lot of manual work done by the watchmakers. if we look at
the photos from others, there are no washers under the balance screws. Of
course the quality of your pictures are way better and it is easy to pot those
details.

You are not only a wizzard in tuning 3303 bracelets, you are a genius in
taking macro photographs.

thanks for contributing this most interesting shots.

Thank you Cromagnonman.

I have this watch about 12 years in collection and I spotted an older photo,
it shows another uncommon detail.

The former dial was without any script and I kept it. I will compare it to
similar IWC dials, because two uncommon details are strange ?!

Heiko
