Is the only difference between the EZM1 and EZM3 the hours printed on the dial?

Hi

There is more than meets the eye with the EZM1 and EZM3:

EZM1

Model designation
EZM 1
Model number
503.010
Clockwork
Lemania 5100
Work elevator
Mechanism
Lagersteine
17
Half oscillations
28.800
Encasing material
Pure titanium
Glass
Sapphire
Soil
High-grade steel screwed
Pressure strength (bar)
30
Housing diameter (mm)
40
Housing height (mm)
16,5
Volume impact width (mm)
20
Kind of model
Assignment measurer
Limitation
No​

And the EZM3:

Model designation
EZM 3
Model number
603.0609
Clockwork
ETA 2824-2
Work elevator
Mechanism
Lagersteine
25
Half oscillations
28.800
Encasing material
High-grade steel
Glass
Sapphire
Soil
High-grade steel screwed
Pressure strength (bar)

Housing diameter (mm)

Housing height (mm)
13
Volume impact width (mm)

Four main take-aways:

1. EZM1 has the Lemania 5100 movement (no longer available to non Swiss watch makers) and is a chrono.

2. EZM1 is all titanium.

3. EZM3 has Argon gas where the EZM1 does not.

4. Oh and the EZM1 comes in some special ZUZ military designs and costs a small fortune...

Hope this helps

Thanks deano. That's exactly what I wanted to know.

Pardon my ignorance, but shouldn't Ezm1 have Argon gas ?

You are correct Sir! It does.

I bought the EZM3 when i could not find the EZM1 but its just not the same!!!

 

[Crusader]

There is one more crucial difference: The EZM3 has special antimagnetic protection to 80'000 A/m, the EZM1 does not.

3. EZM3 has Argon gas where the EZM1 does

Man, those EZM1's are amazing!! I wish they would make the EZM3 with a chrono and Ti...that would be a sweet watch even if it didn't have the Lemania 5100 movement.

Yes yes a reissue EZM1 with a 7750 or relevant SZ movement....:-!

The EZM3 has an inner soft iron case as well, giving anti-magnetic shielding for up to 80,000a/h and is water resistant to 500m, and has a 'normal' diving bezel. The EZM1 doesn't, is WR to 300m and has a countdown timer bezel (and non-screw down chrono pushers which require a little care not to push if diving if you don't want to flood your watch). I love the EZM1, but it's a bit thick at 16.5mm. Having said that, if I saw one for sale, I'd consider buying it!
