aviator ball ii engineer master

Engineer Ball Engineer Master II Aviator
As some of you may know, vintage Ball watches are very good value to buy. Selling a ball is another matter... But anyway, here is my much loved Aviator (NM1086CSJBK), I think from 2011.

There is a 44mm “Asian” Aviator that was sold in the United States in 2010 and 2011. It is called the “Asian” because the watch is smaller in case size than the 46mm Aviator normally sold in the American market; also because the watch operates under the T25 tritium license, which is the only license available for several Asian countries. The watch has the "Webb C. Ball” on a steamloc engraving particular for the 44mm edition. Wright brothers Kitty Hawk is on the 46 mm version. 

Tritium tubes (T25 - lettered on the dial)  made by MB Microtec (engraved on the back - also Swiss made and licensed by the US Nuclear Regulatory Commission) utilizes tiny gas tubes of gaseous tritium (GTLS or Gaseous Tritium Light Source). Although costly - tubes can cost up to $10 each - and having a 25 year shelf life (like radiation, it’s glow will grow less intense over time measured in half lives, but never fully disappear), the GTLS system is superior to Superluminova in that it does not need an outside light source to charge it. This is the source of “Night Vision” watches as well as many similar products made for both military & civilian use.

Better response on post RE: Ball Engineer Master II AviatorAnd here are some updates...

What a beautiful watch! It is better on a strap by far because of its size I think.
I decided to post some strap options for this watch as I find it can be hard to comfortably fit 44x52x14mm on the wrist! This has taken me a while but I finally settled on a simple calf strap.
