6263

[vlydog]

Hello RWG

What would be the most accurate crown for a 77/78 vintage 6263?

702?

Thanks

i keep hearing different things...twinlock 702....than triplock 703.....i belive around late 1975 daytonas started switching over to the 703....but hey....who am i one to say?

It would have left the factory with a 24-700, but, today, RSCs would replace it with a 703/704.

Thank you!

I think 77/78 will already have triplock crowns, only very early 70s models were issued with twinlocks. Generally speaking I would expect all versions with red Daytona printing to have triplock crowns installed (74/75).

I think the 77/78 era was a 702 crown and tube. Page 157 in "Rolex Daytona-a legend is born" refers to a 701 triplock crown in 1972 and by 1977 it refers to a 702 crown. Around 1982 a 703 is used. Prior to 1972 would have been the 700 twinlock. This is all on pages 156-159 of the book.

CONCISE yet VERY INFORMATIVE.

Thanks for sharing the knowledge Al. I think this two liner of yours will remove all ambiguity about this confusing subject

So I imagine its quite possible that a 6239/6241 would be sporting a 703 crown.

[freddy333]

Unless installed by an indy watchmaker, a 6239/6241 (non-Oyster) Daytona would always be fitted with a 6mm Twinlock crown. I believe Triplocks only began to appear on later, Oyster models like the 6263/6265.

But it's not unreasonable that a service would have placed a 703 on a 6239/6241. I'm trying to gather the final parts to my PN...

[freddy333]

Because Triplocks were never spec'd for non-Oyster Daytonas, Rolex would never install 1 (until/unless, at some point in the future, Twinlocks become unavailable).

[danielv2000]

So my best bet is a 702... Going to get pricey.

Are you saying that you plan to install a 702 on a 6239/6241? If so, then that's wrong. You won't see a 7mm crown between pump pushers.

[flex]

yeah i agree.  always a 6mm crown (twinlock 600) for 6239/6241

[danielv2000]

I understand. I just can't seem to find a 6mm Twinlock. I recall a year or two ago, I had a Spinmaster 6239. I can't recall what he put on there as a gen crown. I have to imagine it was triplock.

Something like this?
