Hi Guys,

I just grabbed this Jumbo last week. I didn’t hesitate for a minute.

It has a 30L movement and 12,2M serial which dates it back to 1964. I’m surprised how big it wears. Loads of wrist presence.

I wonder what’s that dial called? Plays amazing with the light on.
Any additional info on the watch would be appreciated too. ref. 71651

Longines will send you some decent information if you request an Extract of the Archives.

Good for you!

I admire the 30L movement and that dial adds interest.

I red somewehere on the difference between 30L and 30L chronometer movement, but can't figure out which one is mine. I sent a request to Longines, hope they'll send me some info.

It looks like an ordinary 30L to me. The chronometer-grade movements have a squared-off stud carrier and regulator tail. Moreover, the chronometer-grade 30L movements are uncommon, and would generally be found in a watch marked chronometer/chronometre on the dial.

Here is a good thread to read: https://omegaforums.net/threads/longines-30l-variations.95910/

It turns out that chronometer-grade caliber 30L movements came with or without Breguet overcoil hairsprings. Still, I imagine that a small proportion of 30L movements with flat hairsprings are chronometer-grade, whereas a moderate-to-large proportion of 30L movements with Breguet overcoil harisprings are probably chronometer-grade. I wonder if @Rumar89 would agree?

Yes, exactly. If the dial isn't marked "chronometer" and the movement has a flat hairspring, there's absolutely no reason to suspect that it is a chronometer-grade movement.

Absolutely agree. Flat hairspring chronometers are much less common. The majority that I’ve seen come from the UK market.
