bought this pre owned Ball.... a special one... with mechanical thermometer !
THE ENGINEER HYDROCARBON TMT TI LE

42mm titanium case with st steel dive bezel
300m water resistant
7500gs shock resistant
black dial
st steel hand
tritium gas tube on hour marker and all hands

the bezel is fitted with tritium tube at 12, the other marker are all luminous... lume is poor... but ball upgraded this in the latest spacemaster!
the construction of the bezel is simple, bezel a layer of rubber feel luminous ring and the st steel bezel insert...

the bracelet also mixed of titanium and st steel
the thick double clasps buckle with diver suit extension is made of steel, very well built, but ball against upgraded to butterfly style in the spacemaster which i dont really understand, butterfly clasp is difficult to wear... so i'm very happy with this buckle!
this ball bracelet like i said before in my previous review on the chronograph... is one of the best built- solid, comfortable to wear, top glass finishing!

nothing special on the st steel caseback
but its nicely engraved
laser printed all necessary information and a temperature scale
of cause this series of ball is antimagnetic.... not up to iwc ingenieur and rolex milgauss spec... but good enough for daily use !

the patented crown guard, ball engineer hydrocarbon trademark !
ball upgraded this on the spacemaster, no more long crown... but i prefer the old design, it look better and technically it function well
but heard the reason of upgrade is to reduce the crown length so that it wont touch your hand and cause the discomfort...
since i dont hv such problem so i just prefer the crown guard...

the date is relocated to 1 for allowing space for the thermometer at six... why not at 12?

no big issue, but i just dont use to look at one.... its little small, left more space for the ball 1 hour marker tritium tube !
so a magnifier is fitted!
the dial is black finish roughly instead of mirror black... which i like... some like the sunshine engraved....

the most important / highlight of this watch is this... the not really useful
THERMOMETERbut who cares.... its unique !
and the index also has tritium lume... not sure how it was constructed !
looks like sandwich construction, meaning a layer of thin layer of tritium gas dial at bottom, a black index dial with opening on top!

sorry for poor lume shot... my tripod is broken....
but for all the ball owner.... we all like tritium / h3 gas tube right?
i'm proud every time i walk into a cinema!
final words... another well built watch from ball... with the unique touch!
the titanium used on reducing the overall weight is + point to some ppl.... but i still like the a full steel case!
i've not time the watch so far... not a guy who measure my watch accuracy everyday!
i felt very satisfy with ball once again!

PS - sorry i didnt wash the watch before i shoot it.... its bit dirty on the sapphire crystal, bracelet, caseback....because im too excited when i got it!
