A case primer for the Rolex 1675 - "Unpolished"

May 13, 2012,10:26 AM
 


We all know that the dial condition is essential to the quality of a watch.  And then next thing is the case.  How many time have you heard the claim unpolished case.  Probably more times than you can shake a stick at. How can you tell if a case is truly unpolished.  Well, be the original owner with a very strong memory.  Or  try and use your best judgment and follow a few simple guidelines.  Simply I wish. I will say however, unpolished case are probably 1 in every hundred that claim to be unpolished. It really is a rarity. 

Can RSC recut the lugs and give a great beveled look again sure but you lose some metal and you lose the flatness that an unpolished case enjoys.  I don't even think that getting out a set of calipers can guaranty accuracy of the unpolished claim.  Rolex case lugs are asymmetric.  I know that sounds a little off in a world of precision machining but the reason the lug shape is different on the crown side is to accommodate the crown guards so that side of the case does not appear out of proportion.  I think we all have noticed this but think it is either our eyes playing games or an overly polished case.  Polishing will make it narrower but for the purpose of validating an unpolished case you can expect to have a slightly smaller lug shape on the crown side.  So putting the odd shaped lugs to bed we move on to how can we figure out what an unpolished case should look like.  By example.  You need to see a good example and compare it to another that we assume to have been polished.

 

 

 


The problem is having a chances to see example so that you have a reference point to help you evaluate what you have seen with what is in front of you.  I was lucky enough, after several watchmakers evaluation of the case, to take a few pictures and share some of the points that were made to me.  The two watches in question are a 17xx mil from around 1967 and a 200xx from around 1968 with the latter being the one "Unpolished".  The one with the bracelet mounted is obviously the unpolished watch in question form 1968.

 

 

 

 

 

 

Again as we know nothing is for certain with Rolex but comparing these two examples can give you at least a feel for what to look for in comparing cases.  

 

 

 

 

 

 

As always having the piece in your hand is really helpful.  You can feel the sharp edges on the underside that are so sharp they can almost cut your finger. 

 

 

 

 

 

 

The position of the lug holes in comparison to the edge of the lug bevel also really counts for a lot.

 

 

 

 

 

 

Obviously the thickness when comparing two cases is a solid indicator.  Not so much in the asymmetric aspect but actual heft is apparent side by side.

 

 

 

 

 

The "meat" around the crown guards tells a story also.

 

 

 

 

 

Clean line and flat case side.

 

 

 

 

 

 

I hope these pictures can help you in the future to , evaluate, appreciate and understand the condition of a case whether it is unpolished, shirt rubbed, or recut by a master watchmaker.

no matter if it has been polished. The information I put up was more of a guide or a standard to measure against other cases and the one I compared it to looks great by itself nice and thick lugs with a worn bevel. But when she stands next to the bench ma... 

Very helpful article, Bill.

Even if I am always " in doubt " when I read the words " Never polished ". I'd say that the watch you show is a superb example of a case in awesome condition. Has it been very lightly polished before, it is hard to say. The tactile test is also important,... 

The feel of the case in your hand counts

In addition the watch has a very tight bracelet I 70 that is almost unworn which is also anecdotal evidence that this watch has had very little use on the wrist. I would say it is 10% used. No matter how good the watchmaker is he has to remove some metal ... 

Great comparison post..

... I don't miss anything, but for the sake if it could you add the actual thickness in mm or any other measure. Because for sure if a watch is getting polished will there be some material taken away. What is left, is less than what it should be.. I'm unf... 

Case measurements

These measurements are conclusive in sofar as comparing these two example but there is no standard to measure against. If anyone has a similar 1968 1675 pleas try and add some measurements. The last picture I borrowed from the web Credit to Anatol. You ca...  

This could almost be a thread in itself :-)

For we novices, this sort of information is paramount when looking for a new vintage piece. I also learnt that the lugs on the crown side were of a different size to the other side. Regards Tony

Always a pleasure to share

 
 By: Bill : May 13th, 2012-17:16
Whenever I can find interesting aspect that I have learned I always enjoy sharing them in the same way you and the other members here do. It was an unusual opportunity to find this prime example and I happened to have the camera ready. Best Bill

Wonderful post Bill....!

What constitutes a 'polished'/'unpolished' case? Would you classify one which was done 'at home' with a polishing cloth as one? and how much 'polished' could one be done this way? Usually I would take this as 'shinning' rather than polishing. So if such s...

There are no hard rules and experience is our only reference. To answer a few of you questions. We are talking about watches that are 30, 40 or more years old so even unpolished comes in many conditions. This is not like factory new watches where we stres... 

Thanks for the clarification Bill

you've provided us alot of basic tips in fact, they're applicable to collecting all vintages. I'm learning everyday! Thanks Bill Mech.

about 'fat lugs','unpolished' into perpective. Your pictures illustrate the point clearly. Thanks for the heads up, very useful information to digest, especially when on the hunt for 'vintage'. cheers fernando

This is not to say unpolished is king

 
 By: Bill : May 13th, 2012-17:14
Or that unpolished is the best. Really you want a good example that has not been overly polished. The lug holes are nice and round with a nice space from the edge. A serve by an expert watchmaker can do a great job in restoring watches with only a small a... 

Having just re-read your post Bill...........

I now realise how much very useful information it contains. IMO this post should remain, fixed to the right of the forum, as a quick reference guide for any member considering buying a vintage Rolex Regards Tony

Agreed - Good reference material should be linked

There is a feature on the right column. I am sure it will be applied. Thanks for your kind words and support. Bill
