That's nice focus! Did you use focus stacking? This Patek 260-caliber movement is nicely done, a nice continuous line of curvature. No sharp interior angles - none were really necessary, and the 240 movement it replaces didn't really have any neither, so nobody can claim Patek is taking anything away.
Not to say I don't appreciate the 260, of which I am definitely a fan, but one of the 240's features is its delicious thinness. Patek used to take advantage of that--look at the 3940 case! They'll never be able to produce a watch like that with this as their base movement.
The 240 is technically thinner than the 260 caliber. The 260 caliber also has a smaller balance wheel - I like bigger balance wheels with the 21.6K VPH slower beat. But the trend has been going towards smaller balance wheels with the faster 28.8K VPH beat. The 240 caliber also works rather well - as a base movement too! The 260 caliber hasn't really fully replaced the 240 yet. Even the new Cubitus movement in the 5822P is driven off the 240 caliber - logically I would've expected this mostly new movement to be driven off the 260 caliber.
Ahh, you bring up a good point. Let's compare the 5140 and 5236 models a bit more closely.

So, the base caliber 240 and the base caliber 260 are 2.4mm thick and 2.6mm thick respectively. So, theoretically, a time-only watch would have a movement around this thickness; and the difference is only 0.2mm. Now; the 240Q and the 260 PS QL have modules on top of their base calibers. The perpetual calendar moonphase module on top of the 240Q only adds about 1.5 mm! Incredible! The perpetual calendar moonphase with small seconds module added onto the 260 base module more than doubles the thickness! So it's not entirely fair nor accurate to compare the whole thing to the whole thing; since the newer perpetual calendar module has the in-line display that does take up more space than the old perpetual calendar module that came out in the 1970s/1980s in the 240 caliber.
It's kind of amazing that there's such a big height difference between the two; despite they're both the same complication! And this is why I really like the 5140. The 5140 and 5236 are both "slowly moving perpetual calendars" meaning the hands or the discs move slowly and take hours to fully indicate the correct information. I would've expected the 5236, being a very new and modern movement, to be nearly instantaneous or instantaneous. ESPECIALLY with all that height increase!
Oh! Sweet picture! Your camera and lens set up allows you a fairly wide depth of field then!

When the powers at be made me a moderator 15+ years ago, the powers at be said they liked my writing but I needed to work on my photography. I'm sad to report, my photography skills have not improved as much as I'd like and are very much below yours!
