Going trough some dark and dangerous alleys

Some distinctive landmarks of my city

He he! Mexico City's WTC looks like the biggest Single Malt Flask to me... yummy!

I even had a plane to catch...well, in my picture at least

All this to get to this place: Mexico's famous Central de Abastos (Supply Central) where you can get the most fresh and tasty raw material for cooking a delicious food.

Lots of happy faces here!

Be patient please, I'm getting to the horological point

My friend Felipe cleaning something for us...

Well... and what does this have to do with watches and HOME???

Because I was wearing this!

because my companion is nothing more than this old gentleman:

Mido Multifort Automatic Bumper Sweep seconds Calibre 0917, 17 jewels, the only large-scale produced regulator featuring a free oscillating hairspring. The end of the spring is fixed between two rollers, adjusting actually its length. No isochronism error by the gap between the regulator pins. Nice feature, eh? Serial number 1349656 gold cap case, with a little wear at the end of the lugs and a lot of bumps and scratches, otherwise, a nice vintage watch. I have to do more research to find out what year it was made. Acording to some expert at other forum it is between 1949 and 1953.

Well, this old gentleman has a two tone dial, really gorgeous, you'll see, and an adorable (to my eyes at least) big crow that looks like a golden sun.

Key Points from the Discussion

The Mido Multifort Automatic Bumper Sweep Seconds Calibre 0917 features a unique free oscillating hairspring, where the end of the spring is fixed between two rollers to adjust its length, eliminating isochronism error from regulator pin gaps.
The movement's multi-level design and the integration of the bumper rotor are notable technical aspects, though a bent bumper spring on the author's piece requires repair.
The two-tone dial of the Mido Multifort exhibits a beautiful patina, with its central part appearing darker or brighter depending on illumination, adding to its character.
The Mido Caliber 917 is a 10.5-ligne, 17-jewel movement with a monometallic screw balance and a self-compensating hairspring, featuring automatic winding in one direction via an asymmetrical swinging weight and energy transmission through a ratchet.
A fellow collector shares his own 1964 Mido Multifort, noting its full rotor auto movement also has a freesprung balance, which was challenging for his watchmaker to regulate.
Watches are often cherished not just for their intrinsic beauty but for the positive associations they hold with family, friendship, good times, and life experiences.

I like the multi-level design of this movement, the way the bumper rotor integrates with the rest of the mvt and that particular free regulation system, but one of the bumper springs is bent so it has to be changed. If someone has more info about this movement, please share

And I love the patina of the two tone dial, Sometimes the central part looks darker, sometimes brighter, depending on the ilumination. I like to think that it looks like a shy watch, it looks like it blushed!!!

This humble but tasty meal: Shrimps and oysters (I wish they were Rolex, he he) in a spicy and sweet sauce, it is made with chily, spices, vinegar, ketchup, onion, coriander and advocado, and a spicy hot snapper and shrimp soup. Not quite a boullabaise, a humble but tasty mexican meal accompanied with mexican beer of course!!! (I forgot to take pictures of the beer and the watch, sorry!) You like some? You're all invited! C'mon, take a good bite Cheers! René Salsa bruja (witch sauce)
