RAF CAMERA WATCH IWC CALIBER 89

HI, DID THAT WATCH HAVE A HACKING MECH? I HAVE A MK 11 WITH A CAMERA WATCH CASE BACK N.I.312 AND HACKING FUNCTION ABSENT.I'D LIKE TO KNOW MORE. JUST CURIOUS,BOB.

Hi Bob,
Welcome to the forum, the best place to discuss things IWC.
I believe that all cal 89s on the camera clock 10AF/807 should have the hacking function. Mine, N.I. 259, does.
What is the cal 89 number in your 10AF/807?

Hi Clepsydra, To much of an amateur to take off the case back but PICS from sales section MWR(marginally legible) 10-08 2014 08:44 suggest 121233.Thanks for your input, Bob.

Hi Bob,
There is a number missing on the movement; it should have seven digits.
I am convinced that all the camera clocks of the Lighting weapon's radar have the hacking function, as it would have been important to know, up to the second, when the missiles were fired. I have, however, learned to never say never.
If you are not comfortable unscrewing the caseback, ask a watchmaker to do it for you. You should be able of reading the movement number, and check if the "broad arrow" is engraved in the bridge.

Each 10AF/807, which is original, does hack, as it is a modified 6B/346 Navigator's Wristwatch Mk. 11 and its RAF spec asks for the hacking feature.

For details see the article in the Horological Journal Dec 2005 p. 468 subsequent.

Responses by Clepsydra and MR. Koenig much appreciated. There is an engraved broad arrow on the bridge and the 1st 6# appear to be 121233 the 7th hidden by a shadow. I now know that my 89 has been dehacked but it will remain my favorite. Many thanks, Bob.

Currently, there is camera watch with Knightsbridge Auctioneers. They have informed me that it does have a stop second lever. Question resolved. Bob.
