Alpha and omega of the EZM1
Discussion
The EZM1 needs little introduction, a Lemania 5100 powered watch designed in collaboration between Sinn and officers from the German forces for use by the newly formed Zentrale Unterstützungsgruppe Zoll or 'ZUZ' Customs intervention unit (and the sister ZTZ technical support unit) in 1997.

Sinn had a history of supplying issued watches to German SF with the EZM2 being used by the maritime operations unit of GSG9:

The initial issued watches featured a 'ZUZ' bow and arrow logo on the dial, 22 of these were made. Sinn then also sold the EZM1 to the public with a '3H' dial initially. A few years later the 'Ar' dialled version was released which featured SuperLuminova indices instead of the Tritium (3H) indices.
In 2007 Sinn released the final 250 EZM1s as a limited edition with a few other upgrades over the 'Ar' including a captive bezel, larger lume pip and numbered case.
Interesting to compare the first ZUZ version and the last LE EZM1...
ZUZ 503.0169 - first batch of EZM1s made, with the bezel that has a slight off-set on the pip - later rectified for later 3Hs and the Ars.
LE 503.3187 - last batch of EZM1s made, so about ten years and about 3,000 EZM1s between these two.
The bezel insert numbers on the ZUZ are less shiny than the LEs, and also the insert itself is much more matt - not that the LE was shiny really, but the ZUZ just seems to soak up any light. It's slightly greyer as well and the numerals slightly slimmer.
^ Note the bow and arrow ZUZ dial logo^
The crystal profile is much higher on the ZUZ than the LE - I think the Ar was an intermediate height. The ZUZ has an a/r coating inside, but none outside. This makes the red dial script just a tad more pronounced on the ZUZ.
The 3H dial lume has gone a lovely colour, which seems to jar a little with the SL hands, but I like it - it adds a little colour and displays its age. There's not much degradation in terms of lume - the pip seems especially bright but was perhaps the thickest SL layer on the watch.
The older one is a slightly darker titanium than the LE - I think that's as a result of ageing of the titanium.
The EZM1 was replaced by the unit in 2001 with the Tutima Commando II, another Lemania 5100 powered watch and again with modifications over the standard (this time adding a bezel).
Here are the two issued ZUZ watches together -
