Info about AP and Rolex ETA movement

[ressmeplz]

Evening all, can someone explain me why the AP Diver mount an ETA 2824-2 and the Rolex bp submariner C mounts an ETA 2836-2? I don't understand why they put a daydate movement on the sub...  Tnx a lot

[kbh]

Most Rolex Subs use the 2836-2 movement because that movement comes standard with a taller canon pin set than the 2824-2 and they just remove the day wheel. It gives more clearance for the hands on the dial markers. No big thing.

What do you mean "mounts"?  and what do you mean why do they put a day date movement in a sub? ETA 2836 movts arent daydate movements. If i remember corectly eta 2834 is a daydate movt. 

Eta 2836-2 is a daydate movement, look at eta site

Btw, my english isn't so good, by "mounts" I mean "the movement they have inside"

Even I got that

Besides the taller canon pinion It''s bases on availability. As he 2824 and 2836 are almost the exact same apart from the aded day function on the 2836 they use what ever they can get their hands on. When it comes to quality both movements are the same.

So, for example, I can switch my 2836 with my 2824, if I change the dateweel?

 

tnx

If the hand clearence works out, yes! Also the stem hight is slightly different but most tubes have enough tolerance to accept the difference.

I think I'd say "some" rather than "most" but yes, generally you can swap

It is also a money thing in manufacturing, if you design lots of watches, day date, date no date, gmt around one movement then you simplify the manufacturing process and the stock holding by only needing one movement type.

 

it happens alot, take for example the BMW X1, they  all have the same engine, software ect but it is not set up the same in all models, so in principle they bult the same car just the power is swiched higher in some models. 

 

Apparently the VW group WILL start fitting and building all cars the same, GPS, traction control, power ect you just pay to have it made available to you, I am sure there will be a big market in Jailbraking cars soon
