Then here's what's amazing ...

After figuring it should be possible for it to weigh 23g, it's surprising to see a weight of 41g clearly shown on the scale! Are you sure there isn't a weighing pan or something that needs to be subtracted? In other words, what weight is registered after the watch is taken off that white weighing pan? If that white weighing pan weighed 20g then it would all make sense, because then the weight would be 41g-20g=21g.

Another way to look at it ... Suppose I could put the polyurethane strap on my titanium RM010. Then, my RM010 would weigh 65g - 5g - 7g=53g. Then, we'd be doing an apples-apples comparison of RM010 to RM035, since they would have the same strap. If so, then at 41g for the RM035 versus 53g for the RM035, the RM035 would not be so much better.

If the RM035 is really 41g, one has to wonder why the effort to create a new case out of the ultra-light magnesium-aluminum alloy. Without even developing a new case material, the RM010 could have been simply modified by removing the rotor, making the case thinner (as thin as RM035, since the rotor is gone), and with a polyurethane strap. If that were done, then without even resorting to magnesium-aluminum alloy, it would be possible to develop a new ultra-light manual wound watch based upon the RM010 with the following weight: 65g (RM010) - 5g (rotor) - 1.4g (thiner case - move savings than the 0.57g savings, since it's less titanium versus less magnesium-aluminum) - 5g (polyurethane strap) - 7g (titanium deployant)=46.6g.

So, such a watch at 46.6g would weigh not much more than the RM035 does a 41g, without even needing a magnesium-aluminum case!

If Richard Mille were to offer such a variant of the RM010 in titanium that is manual wind, with a polyurethane strap, and weighing 46g, I'd definitely interested, since it is only 5g heavier than a RM035.

On the other hand, if the RM035 actually weighs less, because maybe the white pan needs to be subtracted to yield 21g for RM035, then the RM035 starts to look much more interesting that the variant of the RM010 I was just mentioning.

By the way, I don't think there is any significant difference between that auction version and the production version. At least none of the differences would account for any weight difference.

How much RM035 really weighs

 
 By: gls : June 4th, 2011-03:28
I've seen greatly varying accounts of how much the RM035 weighs. In this forum, 35g is mentioned. On various versions of the announcement I've seen both 41g and "under 20g". On Richard Mille's web site, the specs for RM035 list the exact weight of the mov... 

Very scientific!

I just believed this number measured at the boutique with the correct strap and the buckle on. Says 41g. But this was the auction piece with white model number. So, that may be a bit different.... Interesting to letting us wonder about this Bottom line - ...

Good point.

.. but I was there and the scale was showing "0g" before putting 035 on. So, let's hear what Stephen will find out when he gets his one! Ken

Sure thing Ken! [nt]

The RM 35 is 15 grams weights to the 27, and assuming if we take even the lightest weight of the 27 that is the watch without the strap which is 18 grams, you get 33 grams. That is believe is the weight of the 35's case, and makes sense if you plus 2 from... 

don't want anyone to think I'm criticizing RM035

I'm just trying to make some sense of why it weighs a lot more at 41g than the 23g I figured it ought to weigh. I just assumed that the ultra light-weight magnesium-aluminum alloy was used to make the case much lighter. It still doesn't make sense to me t... 

this explain the mystery

Recall that I computed the volume of the RM010 case based upon a difference between the weighings of my titanium RM010 and a friend's white gold RM010. Although I weighed mine precisely to within 1/100 of a gram, it seems my friend's weighing was not so p... 

As far as I understand it...

... there is no difference except for the white model number. Should "33.6g" include strap/buckle? Sometimes people talk about the weight with/ without the strap, at least in case of 027... Ken

weights with and without straps/buckles

Ok, if there is no difference between the auction version of the RM035 and the regular one, then I still can't account for the difference between 33.6g and the measured 41g. The 33.6g does includes everything, so it includes the strap and buckle. I've rea...

I'd turn out to be an even happier man! Whatever the final results are, the lighter it becomes, the better! Also i have a scale newly purchased ready to measure this beauty the moment i get it, so do stay tuned and we shall see what the final production v...

When will you have the RM035 and be able to weigh it? Greg

I'm hearing things all the way

 
 By: BluNotte : June 4th, 2011-18:31
From as early as September all the way to November! Who knows?! But rest assured that i will do the weighing and post the shot soon after! Cheers Stephen
