A Few Double-Signed IWC Ingenieur (666 and 866)

I have shared my Tiffany-signed 866 before HERE, but I recently purchased a double-signed 666AD that I wanted to share.

After I sold my last 666AD, I thought that I did not want to add another 666AD to my collection. I am not a fan of watches without quick set date. However, when this one showed up I could not pass it up. The dial is in quite good condition for a tritium dial - for whatever reason, I noticed that 666s with radium dials typically have less lume degradation than tritium dials. The case also appears unpolished. The icing on the cake was the Turler dial, which I think pairs nicely with the Tiffany. I know @Mods has a nice Turler signed dial as well. Any others in the OF community?

Now that is a Nice pair you have 👍

Congrats on the find, great pair. A 666A is on my target list, preferably with numerals but tough to find

Haha you beat me to it ;-)


Yes a 666A would be great but they seem to come up less often in nice condition. I've owned one before and preferred it to the AD.

Those look fantastic, I would love to add an 866 to my 666 as you have done in the future, but those blue dials cost a significant premium!

Was this the Turler on auction in south america recently by any chance?

Sorry, just seeing this! Yes, that is the same watch - I am surprised there were no other bidders on it. The seller's photos were not very good and did not show the watch well in my opinion.

There was some debris on the dial, which ended up just being some lost lume from the hour hand. It cleaned up quickly and easily with some Rodico.
