IWC Ref. 5310, the "Zodiac" watch.

Among collectors the p.w. ref. 5310 is virtually unknown.
It is one of the finest pocket watches made by IWC in the "revival" period of the p.w.'s, now some 40 years ago. I wrote a short article on it of which the watch pictures as well as the lay-out were made by "hebe".
He is the only person who can make pictures of this kind.

Adrian,

Really fascinating and a great read.

One day I'm sure I will venture into IWC pocket watches, and your article has certainly made this particular one an eventual target - I like the zodiac signs on it.

Thanks for the post!

Thanks Adrian, that is one fantastic watch! And the attention to detail - even the pendant ring is 12-sided.

Best regards,

Henrik

On this overview picture one can probably better see the black dots to which the "sun" hand points as well as all the golden Zodiac signs on the ring.
For a better understanding, the golden ring is not coupled to the gear train, but it can be turned by hand from inside the watch.
Kind regards,

That's really interesting and beautiful too.
Thanks for posting

Hello Adrian,

That you for the information and background on this watch. Still an intriguing time when the watch industry was in difficult times.

Iwc produced some very special and groundbreaking pieces!

Thanks! Martijn

And ps that dial is so beautiful made!

Very informative Adrian. It was a pleasure to read it. What a great watch!

Here another detail of the dial made by "hebe"

Usually, those Zodiac watches are bigger.

An example from the French Jura.

Excellent read and pictures, thanks !

Thank you, Adrian and Hebe. That's another modern pocket watch to track down for the collection.

Adrian, Heiko, thanks for this outstanding post & pictures! As Martijn said, intriguing it was made in those years!

Best,

Bob

Great article, thank you both! That is quite an interesting complication; a different take on a perpetual calendar of sorts. I am curious, Adrian, about the golden ring when you say it can be turned by hand from inside the watch. This is something that should only be done by a watchmaker?

Absolutely fantastic watch. Thanks Adrian for the interesting read.

Cheers Chris

Hi Ben,
Yes, IWC recommends clearly that a watchmaker should do it.

Thank you Adrian,

Great and very obscure watch from IWC. It is pretty big, as I remember.

Thanks, Adrian, for the great explanation once again.
