    Benrus 39 Jewel information please

    I have been watching these Benrus 39 Jewel automatics on Ebay for a few months now. Any information on how those 39 jewels are configured? I have seen information the Lord Elgin 30 but nothing on the Benrus.

    Thanks in advance..

    The maximum functional jewels needed on a wind-up watch is 23 - and even that is stretching it a bit. The other 16 must be stuck in and around the rotor someplace. I wouldn't pay much attention to automatic jewel count over 25 frankly.

    What about manual chronographs?

    True... a chronograph module itself can consume 20 jewels...

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    Not my area of interest but there seem to be a lot of 17 jewel manual chrono models.

    The Benrus 39 jewel is a 1960s time only watch, not a chronograph.

    True, chronographs are often 17 jewels... for example, the Landeron 48 I posted. There is even a version of the Valjoux 7750 that is only 17 jewels.

    But the Lemania LWO283 used by Heuer often comes in a 31 and a 39 jeweled version.

    The most jeweled quartz watch ever made was the ETA 206.211 Autoquartz chronograph with 53 functional jewels.

    53 jewels in a quartz movement sounds like the answer to a question nobody asked!

    the only one I was ever able to find was in an old Sothebys catalog... They had a Dubois Depraz wedded to a doubled up 205.911... a rare bird indeed.

    Actually the Benrus 39 jewel watch being discussed is an automatic watch so this ups the useful jewel count quite a bit. There are many automatics with 28-30 functional jewels. However, the Benrus in question likely has an ETA 2472 movement which has been enhanced with jewels added to the reverser wheels not all of which are really functional.

    Here's an example of the watch in question:
