Need help with 1665 old style crown

[nielest]

Any vintage gods here can chime in on this? I just purchased one of these old style perhaps 701 trip lock crowns from the bay. I was wondering which aftermarket tube ref# i could use this with? Any help would be most appreciated!

Would these work Case tube Ref. # 24-6020 For Rolex: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230380171777&ssPageName=ADME:X:RTQ:US:1123#ht_500wt_1182

here you go:

You have a 702 crown. It's the only crown w/ 3 dots other than the 703/704 crowns. All previous 7mm crowns had no dots below the crown (700, 701).

And marsupilami is your guy to go to- I believe that's his site on ebay!

You can use the 3.0mm x .35 tap to clean out the hole on your case- same as with the 703 tube. But 703 and 702's are not interchangeable.

That's awesome alligoat, anyone got a 702 tube to sell me? marsupilami if that's your site, i just sent you some messages on ebay. i need! :-)

PS: alligoat, what do you mean "703 and 702's are not interchangeable" ?

alligoat, what do you mean "703 and 702's are not interchangeable" ?

A 702 crown won't fit on a 703 tube and vice versa. A 702 was the first 'trip-lock' crown- two o-rings in the tube and one at the base of the crown- nothing on the outside of the case tube. The 703 has two in the tube, one at the base of the crown and one on the outside of the tube.

The 702 assembly came out in the early 70's and was replaced by the 703 assembly around 1980. So when subs like the 1680, 1665 and 5513 go to Rolex for service, it's not uncommon for Rolex to change out the crown and tube to the 703 assembly. Rolex considers these parts serviceable- throw away and replace in order to maintain WR integrity.

Thanks alligoat, great info! If the 702 tube comes without the gaskets inside, is it possible to swap the 703 tube gaskets into the 702 tube? or are there aftermarket gaskets i could get off clark etc?
