The Madrid Codex I. (1490-1505)
1- The Madrid Codex I, also known as "Treatise on Statics and Mechanics" or "Madrid Codex of Leonardo da Vinci", is an important manuscript written by the famous Renaissance polymath Leonardo da Vinci. This codex is part of the Leonardo da Vinci manuscript collection and is preserved in the National Library of Spain in Madrid.
The Madrid Codex I is a collection of notes and drawings that Leonardo da Vinci made between 1490 and 1505, focusing mainly on various aspects of statics and mechanics. It contains numerous detailed diagrams and drawings that explore mechanical concepts, such as levers, pulleys, gears and simple machines. In addition, it delves into questions related to statics, such as the equilibrium of forces and the resistance of materials, as well as annotations on optics and astronomy.
We can find, for example, sketches for an equestrian monument to the Sforza, notes for a water clock and also a design for a hang glider that, as it would later be demonstrated, flew.
The Madrid Codex II
1- The Madrid Codex II, also known as "Treatise on fortification, statics and geometry"or "Madrid Codex of Leonardo da Vinci", is an important manuscript written by the famous Renaissance polymath Leonardo da Vinci. This codex is part of the Leonardo da Vinci manuscript collection and is preserved in the National Library of Spain in Madrid.
The Madrid Codex II deals with different subjects and can be divided into two clearly differentiated parts; the second is the notebook detailing the casting of the Sforza Horse, which was added at an unknown date.

Good quality - not very useful
Good quality utility pouch, downside is no recent phones will fit in this pouch as shown and the strap on the back is useless. Would've returned it but liked that it is waterproof and can hold thin items. Not the best value for the money if you wanted to protect a phone. Zipper is very sturdy. Too thin to be functional.

Color: Black, Style: AEQ110W-1AV
Very, very Nice inexpensive watch!! Kinda tough to set it up but when done its well worth it. The icons glow so no light. The watch is a good smaller on my wrist than I expected but its functional not style Ineeded.
Still a verry good watch, no questions asked!!

Well built under $50 watch.
I got this Casio as my first Casio as I've worn watches since I was a teenager, using non brand sport watches and eventually graduating to fancy Japanese watches. Now I found myself not wanting to use those to put on wear on them because they are automatic and require some maintenance, so I figured it was time I got my first Casio. I was skeptical at first because I knew I wanted a Casio but the designs were all, dare I say generic (Or so I thought) so I ultimately wanted a G shock but, for the price and intended purpose I found this watch that just checked the boxes in design and "10-Year" battery. When I got it in the mail I was stocked, I hadn't felt a resin watch in years and set up was straight forward. Now after weeks of use I've found that through a bunch of me smacking it and hand washes, it still looks new, fortifying my satisfaction in buying this. Can recommend.
