If the black three-hander appears it will be most certainly with SW200…
SW330-2 on the GMT is the better movement in every way.
I would only consider the three hander auto if it comes with COSC movement.
It is interesting looking at the datasheets. Looking at both the SW300 and SW330 there are some interesting take aways.
A standard movement is not available for either movement. They start at Elabore. This means that they are better spec'd at the lower end but also that ALL of these are restricted supply. But here are the numbers:
+- 15sec/day isochronism
20 sec max deviation all positions
+- 5 sec/day on average.
That is quite a bit better than the base SW200 (+-12 sec on average). Even slightly better than the SW200 Elabore (+-7 sec average). Both come at a cost though. The SW300 is 3x the cost of the SW200 standard and 2x the cost of the SW200 elabore. The SW300 is only slightly cheaper than the SW330. This would mean that practically speaking the 3 handers would cost just as much as the GMTs.
There are some other advantages of the SW300 over the SW200 though. One is that it is much thinner. 3.6mm vs 4.6mm. On the divers they could either make them thinner or increase the water resistance with no change in case height.
And of course the 56 hour power reserve.
The datasheets also state that only 95% of a delivery have to meet spec. Here is the actual text:
The limit values are subject to interpretation : 95 % of the pieces delivered in a lot must be within the specified limits.
To me that is pretty crazy. You have to assume out of the gate that 5 out of every 100 movements won't meet spec. That raises the per unit cost.
Anyway some interesting stuff if you dig a little bit.
