Majetek Vojenske Spravy – "Property of the Military Administration"
Majetek was a model ordered by the Czechoslovak military and produced by several different watch companies.
A super RARE vintage watch! And dated around 1939, this is the original Eterna "Majetek Vojenske Spravy" wristwatch, a military watch for pilots. During World War II, Eterna Majetek pilot watches were issued to Czechoslovak Air Force personnel as part of their standard equipment in the late 1930s and early 1940s. In addition, Longines was an official supplier and produced pillow-shaped watches (with a embossed bezel) for the Czech Air Force during the same period.
Inside this watch, there is an original Eterna W. Co. manual winding movement, Eterna 520 caliber, subsecond, 15 stones, 3 ADJ, 42-hour power reserve, Swiss production. This movement is the first Eterna caliber for men's wristwatches.
Eterna W. Co.
It is enclosed in a unique 35.8mm clamshell shell in the shape of a pillow, also called a turtle shell. The case is large for that time period, but necessary to accommodate a large dial for easy reading during flight.
This is probably one of the earliest versions, marked by the absence of two crossed swords in the upper left corner of the case.
It has a black enamel dial (with some patina) with white luminous Arabic numerals, a minute scale, large luminous cathedral-style hands, and a subsecond dial at 6 o'clock. The name Eterna is also indicated on the dial at 12 o'clock.
This watch is in EXCELLENT condition! They walk very well and show great time!

Great way to connect my Ethernet to my MacBook Pro....
Size: USB C to Ethernet Adapter
Needed to direct connect to my Modem / Router, but my MacBook Pro, being more modern, and slimmer, doesn't have an Ethernet port anymore (thank goodness). This worked perfectly; just plugged it in and ripped...definitely Plug-n-Play for my Mac.
Quality is good (what else do you expect from Anker).

Easy to use Plug and Play
Size: USB C to Ethernet Adapter
The item works great. I was having issues with video conference calls even with strong wifi in my house. I bought this adapter due to my HP laptop not having an Ethernet port. This worked great right out of the box. It was detected automatically and as soon as I plugged the Ethernet cable into the adapter, my laptop immediately switched over to that and my internet became more stable.

It's functional but not as fast as I expected.
Size: USB C to Ethernet Adapter
For Android phone Samsung Flagship Galaxy Series phones... at best getting 136 Mbps, which is 0.136 Gbps. But it is working and allowing me to transfer files within my network. No where near a Gigabit transfer.
I will likely keep it because I have another use case for it (a faulty Ethernet on a laptop) and don't get me started with the abyssal wifi speeds on laptops. This deserves at best 4 stars.
