Lanco Quartz

Picked up a Lanco Quartz from a flea market today. To my surprise what was inside appears to be Tissot 2030 movement (or some variation of it) with it's funky date/time setting procedure - which after a change of battery is now humming. Caseback has model- or serial number 75216 M; which I'd guess is model reference number. Just posting this info here as quick search only surfaced one other similar Lanco with no photo of the back / mention of number at the back. Don't think the crown or the bracelet are original - but who knows.

I didn't see on that site how to set the date, but do I read this correctly that there is a 'jump hour' sort of setting to the crown but NOT a minute setting? So you have to use a weird procedure to do a 'fast forward' with the minute hand until it is right? Do you use the jump-hour crown position to set the date like with a GMT master?

How strange of a decision, they must have decided that 'setting the time' was a watchmaker/advanced procedure, assuming the quartz would last 'long enough' to never have to change anything but time zone and date. Not an awful assumption (even those who wear an automatic all the time don't find themselves having to set often either!), but definitely a "feature" that didn't last 馃榿

Interestingly, there is another Lanco for sale here: https://omegaforums.net/threads/1970s-lanco-tissot-automatic-date-75.184347/ though it is an automatic.
Also, this one that sold a year ago: https://omegaforums.net/threads/lanco-barracuda-epsa-super-compressor.174794/

Anyway, really neat, thank you for sharing!

Not so weird, my Omega quartz Seamaster with 1342 movement works very similarly. When it was new in 1982 it ran about 1s per month (but sadly does not on modern batteries) and seldom needed minutes/seconds adjusting, but my job took me from Western European Time to USA Pacific and any point inbetween so the quick-change timezone on the hour hand without disturbing the minutes or seconds was in much more frequent use.

That's not why I bought it though, I just thought it looked good 馃槑

TBF, it looks like quartz-crown-behavior settled by the time I was born, so this IS weird to me 馃榾 Just an interesting piece of history!

I could honestly see how it could be usable/not problematic, so I have no real opinion beyond 'interesting'!

Here is a Youtube video of how setting the time/date works (on a Tissot watch). There is a very distinctive sound that the movement makes when advancing hours - which you sort of can hear on the video too. I had a Tissot 2030 Seastar back in a day and recognized the sound when I was trying to first set the time and had to re-open the caseback to take an actual look at what's in there. I bet tons of these non-Tissot watches have gone to the garbage bin simply because people in 2nd hand stores thought they're broken because they couldn't set the minutes (allegedly this has been a thing with Tissot 2030 Seastars as well).

Oh my! That is super neat! Also, seems inconvenient, but of course, setting the time on a quartz watch is comparatively rare. Thanks for sharing it!
