Hi Jon, I see from your posts you've realised a 1163 could have been a 11-I but not a cal 11-which makes a difference as I don't believe a cal 11 existed in a 1163. That aside, this watch does not appear original. The '15' in the case ref 15630 denotes it had a Cal 15 and is visibly different to the 11/11-I/12 movements.

A 11630 did come with the same Viceroy style dial as the 1163 but this seems to be a mix up of parts. (not in very good condition either, especially for the price.)

Just my opinion but hope it helps.

Best,

Steve

: I need a little help with the Autavia in the link. The calibre 11-I
: and dial/hand configuration look like ref. 1163 but I had him
: send a picture of the ref stamp between the lugs which says
: 15630. All the info on OTD has the 15630 with orange accents.
: Can anybody help determine if it's a redial?
