Just got the Extract from Omega Archive. For those who record such things...my Speedie has a 29,114mill serial number and this dates it to March 18th 1970, supplied to USA., no mention of bracelet. So everything adds up and I am a happy bunny.
Glad I ordered the extract before the Swiss Franc moved. Lord knows how much it costs now.
Can anyone let me know what buckle this would have had originally? Next step...
Originally, it would have been sold with a stainless steel bracelet. Either (bracelet/end links) 1039/516, 1116/575 or 1171/633. The 1039 are easily found on ebay but are expensive, $700+. The 1171/633 is available used for less and is available new from Ofrei.com in the states.
So, if you wear it with a leather strap, you can do whatever you want.
