Thanks for the insight! A few more questions..

Thanks for the insight! I wish manufacturers made it clear that daily winding could be a problem.

I rotate my watches daily so my automatics do not have along enough power reserve between wearing occasions. I have been hand winding my calatrava for the last year every evening to avoid having to reset. The lack of a hack function means setting the minute hand to coincide with the seconds hand is a real pain and having them out of sync on a centre seconds watch drives me mental. I guess I'll have to invest in a series of winders

I appreciate that the 324 is designed as a platform for more complex features but are there any stand-out features which apply to a 3 hand date Calatrava? While it is certainly thinner than a 3135 is it in any more sophisticated? The 3135 has a free sprung overcoil, variable inertia balance , efficient bi -directional winding, excelent shock resistance and an instant date change. What sets the patek apart other than finishing?

Just to be clear - I love my Patek Calatrava and can examine it for hours under a loupe - it's just that hard facts are hard to come by in this industry built on luxury marketing.

Perhaps we should ahve a separate technical thread?

Experts, please !! (5159 perpetual)

Dear all, I just see on my brand new 5159 that this circular piece is not "centered" in the circular hole. Is this a problem ? Thanks for your help !!!...

Not a problem

By: w220 : February 12th, 2012-02:43

That piece works like a clutch (not sure of the correct horological term) that engages and disengages the winding rotor and manual winding. It is supposed to move; it would actually be a problem if it never moved! Try winding the watch manually, and you w...

Great, thanks ! (nt)

Wig-wag pinion

By: CzapekWatchmaker : February 12th, 2012-20:40

This is a wig-wig pinion. A small pinion (toothed gear) is rivited to the underside. It will move inwards when you wind the watch by hand and will be pushed out of the way by the rachet wheel when the automatic mechanism is winding the watch. Try winding ...

I know from bitter experience that hand winding an ETA 2824 movement regularly will cause major problems with the reverser wheels jamming prematurely. I've had several of these movements and each one died in approx just under one year after hand winding d...

First off, hand winding automatic watches daily should not be done. Period. Hand winding any auto watch causes part or all of the auto to spin very fast in a way they are not designed for. I have often recommended against watch winders because they cause ...

Wig-wag pinion

Very interesting, thank you! So this should be the Wig-wag pinion in my 5140 with 240Q movement, exposed so it is easier to see....

Similar but different;) This is an uncoupling yoke (M1165.31-1A.A) This performs a similar function but instead of disconnecting the the rachet wheel from the hand winding mech, this disconnects the rotor from the auto mech. This is because this calibre, ...

I was told by the Rolex tech guy that he usually tells people if your Rolex has been sitting on a desk for a day or two, to give the crown about 60 turns. When he first told me 60 turns, I thought that was too much but then he explained that most people u...
