Jaeger Lecoultre Reverso Classic small seconds Duoface

[Coquinette]

Hi!
Does anyone have purchased this watch yet? Any major flaws? I have my eyes on it but wanted to check for feedback first... Thanks!

This user contacted me in PM first, I told her to open a thread about it, as I didn't want to hold info on this

It seems this release got un-noticed, looks like to be a nice quartz one of this one :

The medium size version of the tribute duoface we've seen released lately.

Measurement seems to be a couple mm shy of the gen, but doesn't seem to bad from the pictures.

This will have a ticking second of course, no idea on how the movement work and operate though

Can someone explain for me why a quartz based movement couldn't be programmed to have a sweeping second hand? The clocks on the school walls back in the day had one..

Just curious on the tech behind it.

It's possible, those movement do exist, you can see them on bigger mechanism usually, but they also exist in some VK quartz chrono watch, but the sweeping will be done only on the chrono second hand.
I don't know but maybe there's a stress / size constrain at play here

I know I'm necro-threading here... but the reason that Quartz watches have a seconds hand that ticks rather than sweeps is to save electrical power. The rotation of the seconds hand in a quartz watch is driven by a stepper motor. Each time the stepper motor adjusts its position (i.e. moves the second hand) it requires a small amount of electrical current. If a quartz movement were to have a seconds hand that "ticked" four times per second (e.g. 28800 vph like most mechanical movements) then the battery would run out four times sooner. It's also slightly more complicated to make a stepper motor that has 240 angular positions (one for each 0.25 seconds) rather than 60 (one for each second).
