Shopping day-dates: strong opinions of WG vs Plat, 36 vs 41?

To your query. Platinum @ 41 would be nice!



Though here is my little daydate....

at first I thought Romans are the only way to go on a DD2, I'm liking those arabics more and more

One day ....

[RobertM]

wg - 41 mm
with white dial.... IMHO.

[Chris B]

36mm PL is my preference, but both are great.
Try them on & see which one takes your breath away

As for the metal, I am a big fan of platinum. Couple of points:

Unlike 18 carat gold (75% gold), platinum is 95% pure platinum, so you are getting more of the precious metal.

Platinum is HEAVY. Do not go swimming with it or it will drag you to the bottom of the ocean Not really, but it has heft.

Of the mined precious (used in jewelry) metals, platinum is the rarest, so rare that all the mined platinum on earth will fit into a regular sized living room, that is how little of it that is available. Gold is a bit rarer if you include all of the metal in the earth that is not yet mined.

Platinum is dense. It will stop cosmic rays from hitting your wrist, although a neutrino or two will penetrate it.

From Wiki: In the 18th century, platinum's rarity made King Louis XV of France declare it the only metal fit for a king.

Other Facts on Platinum:


Platinum is the hardest of the precious metals. It never tarnishes. Its intense luster remains intact over the years and it is completely hypoallergenic. The name originates from the Spanish word platina meaning ‘little silver’. Platinum is the rarest of the precious metals.



Platinum is closely related to five other metals, Palladium, Ruthenium, Rhodium, Osmium, and Iridium. Together these six metals are know as the Platinum group metals or PGMs.



Platinum’s supply / demand fundamentals are tight. In fact, if platinum mining were to cease today, above ground reserves would last less than one year. In contrast, gold reserves would last nearly one quarter of a century. In contrast with Gold and Silver, there are no large above-ground platinum stockpiles to fill the gap against significant disruptions.


Okay, I love platinum. What can I say?

PS: I don't own one yet, but if things work out, I will.

All of the great information and opinion has not made the decision any easier for me as yet...but it certainly has made the shopping more fun!

Please keep the info and advice coming

Platinum on the other hand is famous for galling and if it does then you are up for the tens of thousands for a new case.

My ideal watch would be one with a platinum mid case and a white gold case back, then there is 100 per cent chance of it not galling. Better still is that the case back is less lilkely to strip the threads of the midcase.

Platinum is harder to work with in the event that metal repair is required as opposed to gold.

Interesting info; Although gold doesn't gall, I thought that being softer
it's more likely to have thread damage requiring a new case. It does
make sense that a platinum case and gold back would be just about ideal.
I wonder if rolex uses an anti-seize for the Pt case threads.

Yes, you are right,especially if you cross thread it or put too much stress on it when closing, but the galling has to do with the geometric strucure of the metal crystal as gold is central cubic whereas Platinum is not. The shearing stresses of the metal sliding over each other will cause that kinetic energy to cold fuse the tips of the threads where as with gold, having a different lattice structure it is less likely.

Personally, I like the colour of platinum as opposed to the colour of gold, but ideally I would prefer a combination of a platinum case with a white gold back to avoid any such problems. Rolex uses fomblin as a lubricant on threads, but with Rolex company being a production line pumping out thousands of timepieces per year, human error is always likely to occur regardless of Quality control. A risk I prefer not to take when spending in the tens of thousands of pounds, especially on a timepiece with perhaps one tenth of the value in precious metal.

Has there ever been a single reported case of Rolex platinum cases galling?

Yes!!!, my father's DAY DATE and it was not a very good experience, which I will not go into

Lots of great info here! One day, I'll have a platinum watch, but it will be a long time from now!

I would 100% go for 36mm, YG president bracelet, (model Tony Soprano)

Any pics of what galling looks like??

It is when your watch case will not open due to the threads seizing from been welded up by the friction of them sliding over each other.

See http://en.wikipedia.org/wiki/Galling

Metals prone to this are Platinum, Titanium and aluminium

Gold is a good metal that resists galling. Silver is the best against galling.

One of the reasons I would steer away from any watch made from Platinum and Titanium, regardless of brand. True, lubricants such as Fomblin can prevent this, but, you would be surprised how many watches can be missed during assembly, as once they are closed, no quality control can really tell unless they open them up and inspect each and very one of them.

If galling happens, in many situations, the case needs to be cut open if you want to access the mvt. Rikki from the watchtech section of this forum can support this, as he himself also had experience with this.

Hope this helps

WOW timelord. This knowledge is definitely takin' it up a notch!

I have it on good authority that if a platinum watch is serviced properly, there will be no problem.

And I am quite sure that if the RSC could not open the case during servicing and it was not serviced or opened by an unauthorized person, they would stand by their product.

If this problem were common, no high end watch maker would use platinum. Also, my research indicates that the tendency to gall is related to the metal used in the alloy. I would suspect Rolex uses an alloy least likely to gall.

We had first hand experience with a PLATINUM Rolex day date galling.

Galling has nothing to do with the alloy used, as platinum galls even in alloyed metals, as long as there is over 50 percent of the precious metal,

Galling has nothing to do with how regular a watch is serviced. Even a new watch can gall if there has been a lack of lubricant at assembly. New threads are more prone to galling than older threads.

Gold is better with anti galling properties - even in alloys

Rikki had a problem with a Rolex galling as well and there is nothing magical about the alloys Rolex use.

[Chelseafan]

You better go see ... I went to try on the YG dd2 and it was just too big for me , not physically but aesthetically. The bezel looks overwhelming and the case not balanced with the bracelet. Obviously this is just my unimportant opinion but I think the YG President 36mm was just an all time iconic classic that should have been left well alone. The DD2 has a different look completely , it is far more 'bling' , great if thats what you like.
Now the DD platinum with it smooth smooth bezel is in a different league all together. Georguous!

Been away for a few days; this is really interesting info, timelord,
thanks for sharing it.
