ESA 942.711 24 hour ?

Post05 Mar 2014, 15:03

Does the ESA 942.711 have a 24 hours setting option? I have been asked this and I cant find an answer o the net or the manuals.

I haven't found a switch or something like that, but the back of the circuit sometimes has a tiny "12" or "24" printed on the back. So it's maybe "factory specified"?

I haven't got a better picture, sorry, but you can see in white "24" above the gold colored esa mark. (you might need to zoom in a little :) )

Thanks dutch

It doesnt help that the original longines manual that came with the watch shows a '0' for the first digit. '08.00'. So the client thought the time should be in '24' hours. Does your 24 model state 8 o clock at '8.00' or '08.00'?

I think the only time, or rather occasion when you get "08:00:oo" on the display is in Chrono mode. I think all of the examples in that manual where the display starts with a "0" are taken from the Chrono mode, whether this is clearly stated or not.

Its a silly manual anyway - does the quartz crystal really beat at exactly 786,432 times per second?! Bizarrely 24x the frequency that the manufacturer ESA claim for the movement in their 942.711 Tech Pub.

I've just checked my Certina 24hr watch. 9 a.m. is displayed as "9:00" so not with the extra 0 before the 9. The chrono displays as"00:00".
