I've been trying to compare the dimensions of different pointed crown guards on vintage Rolexes. Does anyone know the width of the crown guards of a 1675 PCG? When I say width, I mean horizontally, basically starting from the outer edge of crown.

Anyone?

There are two styles of crown guard for the PCG 1675.
Early ones have clearly defined points.
Later ones have a kind of ridge thing going on.

Which one are you thinking of ?

I've attached a couple pics of an example. I think these are someone's photos from this forum.

Please take some kind of photo editing tool and mark with a line where you are trying to measure so people can tell.

This is the measurement I need

Wish I could help you, mine is about as rough an example as you would find.

From your picture, you want the measurement from the part of the guard nearest the crown to some part where it blends in with the case. There is a gradual radius where the guard blends with the case, it's not clearly demarcated so it's going to be very subjective when it comes to measuring. Basically any number you get will be meaningless. If it was just the flat part then that is quantifiable.

Why do you need to know this dimension?

Hi everyone. Wasn't expecting all the sudden replies after getting nothing for so long. I'm working on a dive watch project that I will be launching this year. I would like it to share some characteristics from 8-9 different vintage watches, including those with PCGs. I've been going back and forth as to which type of PCGs to use. I'm documenting different crown guard dimensions of the PCG subs and gmts and might perhaps settle on a happy medium. I like the extra length that seems to come with the gmt cases, but I'm flip flopping on exactly how I'd like them to look.

CrownMe · 16 February 2014, 06:54 AM

So you are creating your own dive watch? I hope you show pics along the way. Would be very interesting.

Yep. Will do! The design was complete and factory samples have been coming in. The first sample of the midcase just seemed to have bad looking proportions that I didn't really foresee. The pointed crown guards didn't look right, the crown was protruding too much, lug-to-lug length looked short, etc.

There's something about the proportions of the vintage Rolexes that just look so right, and I've been figuring out what makes it so.

After receiving the sample, I started to reconsider exactly how to do the pointed crown guards. The current design has pcgs that are more like a 5512. I love the aggressive "fins" that are the gmt pcgs, but the pcgs on the subs also have their charm. I'm trying to come up with a compromise between the two. The project is proving more difficult than I first thought.

I think it's great that you are creating your own Rolex style case....as long as it does not end up in the classified section for sale as authentic

not a chance. Wouldn't even pass as a homage watch to most people. Different diameter, lug size, completely proprietary bezel, very unusual dial, and much more. But the inspiration comes from the fine details of vintage divers (and now perhaps GMT too), particularly vintage Rolex. After toying with so many different measurements and ideas, it is really hard to get better proportions than on an old Rolex. The ratios are so right.

Sorry to the OP for my delay in posting this info. Here's a few pics of the crown guards on my 2nd generation PCG 1675 (S/N 875xxx).

Lots of variables when ascertaining dimensions on an old Rolex case. I'd say look at as many as possible.
As I understand it, factory polishing in the 1960's had a real manual component ... so differences would have existed even on factory fresh watches.
Forty years down the track, the vast majority of old Rolex's have succumbed to the polishing wheel (again) at least once in their lifetime.
Many of my watches certainly have. I think the crown guards on my PCG 1675 are reasonably healthy but what would I know

If you are looking at an engineering project, you may like to consult with http://www.laboratorioportanova.eu/i....5513/?lang=en
They do highly specialised case restoration work on various make vintage watches and claim to be able to faithfully reproduce original factory dimensions.

So if it helps ...

.... and ages ago I promised someone on TRF a few pics of side by side PCG's. So if they are still out there ...
