The 6424 Oyster Precision - an unusual large no-date reference

After the Rolex catalog settled down in the late 1950s, Rolex didn't really produce large numbers of no-date watches in 36mm cases aside from the Explorer. In fact, the vast majority of 36mm Rolex oysters from the 1960s through the 1980s are DateJusts and Explorers, and if you want a no-date non-sport Rolex, you generally have to go down to 34mm, where you will find tons of hand-winding and auto-winding references with or without date.

One notable exception is the ref 1018, which is a great automatic (perpetual) no-date reference in a 36mm case. They are less valuable than the 1016 Explorer, but still highly sought after. The ref 1018 is fairly obscure to the general public, but pretty well known to collectors.

In some ways, you could consider the ref 6424 to be a hand-winding version of the 1018, a no-date 36mm oyster. They pop up now and then, but overall they're fairly uncommon. And to be fair, hand-winding oysters are not everyone's cup of tea. For example, many people don't like the idea of unscrewing and re-screwing the crown everyday to wind the watch. However, it's a very thin and light watch, and sits low on the wrist, making 36mm feel larger than you might expect.

Another nice thing about the 6424 is the 20mm lug spacing, and the fact that they generally came with a 7206 Swiss rivet bracelet (early examples will not be marked). Since these bracelets were also used for the sport models, they are in great demand and quite expensive. In fact, they probably have equal or greater value than the watch head itself. One interesting curiosity is that the 6424 has non-drilled lugs, so the bracelet endlinks for the 6424 have a cut-out to access the spring-bars.

Below are are couple of examples I found over the last year. One is a T SWISS T with a circularly brushed dial from the mid-60s and the other is a more conventional silver sunburst SWISS-only dial from the early 60s. Both have lumed alpha hands, although slightly different styles. Both also came with 7206 bracelets and notched #75 endlinks, and TBH, the bracelets are what originally drew me to the watches. But I have to say, they are great to wear.

These look great. The look is just so clean and dare I say so Japanese?

I love that reference, the BIG OYSTER! 75 endlinks are also great fit to slim oyster cases, including the DJ. My OCD can’t handle a bad fitting endlink.

Also don’t forget about the 5504 which is the 36mm Air King And Explorer super precision. I have one from 1959 and a couple of 1018s. They are super comfy.

Good call-out on the 5504 Air-King. Definitely in the same conversation.

Let us not forget the 36 mm grand daddy - the 6024, cal 710. 19 mm lug width and thru holes only on one side. Super Oyster crown. Around 1951-52.

Some old and bad pics showing the wonderful dome plexi and the lug hole "situation".

I wrote about that twice in the post. ;-)

I have been collecting info and pics of them for a little over 10 years and they all have serials starting with 866 XXX (from what I have seen - and when I have been able to verify the serial). That could/would suggest that there were only 999 made. So - do not beat your self up about it being new to you.

I believe they should get more attention collectors-wise - but hey - I am sort of biased.

Beautiful watch. Actually, there are many 36mm references from the 1950s with nicknames like, "big bubbleback," "semi-bubble back,""ovetonne", etc. I couldn't even start to list all of them. The lug holes on one side of the case are an interesting curiosity that one finds in several Rolex and Tudor references from the 50s.

Also, an added benefit to these is you don’t have the auto-winder issues you have with the 1030 movement.

Thanks @Dan S for the shoutout to the 6424. Coincidentally, I also just picked up a 6424 in Tokyo last month, and mine also comes with the 7206 rivet bracelet and the #75 endlinks.

It's a fantastic watch on the wrist, especially with the rivet bracelet. It's noticeably slim, and while it is manual-wind with a screwdown crown, the 58h power reserve means less winding hassle.

A wrist shot from Tokyo, and a recent one from home:

That's a beauty, @NT931!
Thanks! Have to say these vintage 36mm Rolexes are wonderful on the wrist. I picked up a 1600 last year as well and I've realized i like those DJ's without the fluted / engine turned bezels.
