Up for sale (will consider trade) is this very nice 1970s Heuer Autavia ref.73663 KAF. It's a pretty special watch in many ways but also in that only a small number were issued to the Kenyan Air Force pilots and crew with the KAF imprinted on the case back.

Price - USD5750 negotiable - accepting payment through wise.com or direct bank transfer in AUD
International insured EMS shipping included at this sale price or happy to go 50/50 on shipping and insurance away from this price. This has been priced to sell quickly - probably the cheapest in the world, let me know if you find differently. Grail on the horizon...so no point in nickel and diming, just a really fair price, but if you disagree msg me and let me know.

42mm in diameter (excluding crown & pushers) 47 mm lug to lug with 20mm lug spacing.
plexiglass
Reference 73663 with Arabic radial dial
Valjoux 7736 movement rhodium plated with 17 jewels and identified by the three sub registers
Comes with grey NATO strap with orange stripe as pictured only

Some wrist polishing has gone on over its life time and so the imprint is a bit light to see in certain lights. I have places a case back sticker on it to minimise any further polishing.

Watch is in Australia but I have shipped internationally on numerous occasions - we can work it out.
