Info on cannon pin/hour wheel ETA 2824-2

[ravishingrick]

Hi,

I would like to replace the cannon pinion and if needed the hour wheel on a AP RO rep. The standard cannon pinion the watch comes with has a central seconds pin, yet there is no seconds hand mounted. The Gen does not have a seconds function so I would like to replace this cannon pin with one without the seconds pin.

Anyone know where I can find a cannon pin for the ETA 2824-2 without the seconds function or does anyone know the ETA part number?

Regards,

RR

ETA part number 242/1 is a cannon pin wheel without any seconds hole, it looks identical to the 6497 cannon pin gear and has a flat top. You also need the new seconds wheel part number 227/3 as it is designed to fit this cannon pin and has the bearing in a different location than the other one, clipping the tip off the existing gear is not the way to do the mod.

You have to measure the hour wheel first and match up the cannon pin to the hour wheel, to make sure you get the correct length one, they come in 4 different sizes. I have ordered them before for your type of watch and they are available. Just make sure you get all 3 to match, cannon gear, hour wheel, and seconds gear.

Thanks The Zigmeister/Q for the information. The replacement of the cannon pinion and seconds imho is the only way to go.

Found a post from Ubi who carried out the cannon pin/seconds wheel mod himself... Love the results...
