YC II, ref. 3012 with cal. 2405.

I expected a cal. 2250, before I opened this watch. I think, this is an early YC II. The later YC II have the cal. 2250.

Who has some more information about this issue ?

Hi isobars, well, it was an effort to get this watch, as it is now. Aprox five years ago I found this watch on EBAY, but with a strap, instead a bracelet. I tried to order a brand new bracelet. After a long time, it was successful, one of the last bracelets in stock, they told me.

Two years ago the watch got a service, including new SL marks and new SL hands. The result is perfect, a "new" YC II.

An underestimated watch, from my point of view. With a special shock absorber system and even the inner side of the case back is nice decorated.

Hi I think the c.2405 was the 2nd quartz movement used bvy IWC
after the Beta 21 (c.2001/c.2002)

I think it is not an original IWC production.
But it is still from the time where quartz movements got movement numbers. Later the quartz movements had no more movement numbers.

It is the same movement was used as the Jumbo Inge-Quartz
Ref 3003 (I think) and other early IWC Quartz watches

my recent studies

on the Yacht Club II models confirms your statements.

Thank you Ralph,

fabulous information. Indeed, the cal. 2001 and 2250 have no movement numbers.

Some close up photos of those movements. Sorry, the description is in German only.

Cool piece.

3rd numbering for Beta 21 ?

The shown movenment in the other post has 3213 (and 3260 in the picture just above)

It could be the start of a new numbering system.
But this numbering was probably only used for the c.2001
(it could also be the original numbering of the beta 21)

The later version c.2002 had then a IWC number 2'20x'xxx

The 2001 movement in the picture got a replacment of the electronic.
It is the latest version of it. (there are differernt trimmer and itegrated circuit types)

Most excellent indeed! nt.

Wish Mecaquartz was still in the collection >

because there is a definite roll for high-quality watches of this species. And of course, we want them with our favorite name on the dial and movement!

Info on IWC calibre C2405

Hi all,

The IWC calibre C2405 is from the basic Eta 940111 from the family of quartz movements I show here.

However, I would like to reiterate that IWC takes much pride in perfecting most movements they use. In this case the components were bought from ETA but then parts including the plates were modified and/or hand finished in the IWC factory, as can be seen in the photo.

The fact that IWC has done these improvements even on a basic quartz calibre speaks highly of the approach IWC takes to watchmaking.

Our moderator has repeatedly illustrated here on our forum the obvious and subtle differences between an off-the-shelf movement, e.g. Valjoux 7750, and a comparable calibre when used and finished by IWC.

Hope you find this bit of information interesting and helpful.

Regards,
Jack Freedman

Very interesting Info, as always, thank you. (nt)
