Some time ago, Bas van Dorp and I both decided we needed a Lemania 5100 watch. I bought a Sinn 142 St.S at Horloge Platform Nederland in The Hague and Bas ordered a Sinn EZM1. His one was on order, and since the run on the last watches with Lemania 5100 was enormous, he had to wait a bit longer. Last week his watch arrived and here you can read his review on his EZM1.

Bas says: “The guys who came up with this idea will be the first against the wall when the revolution comes, that’s for sure.”
Let me be the first person to volunteer for the duty of being on the firing squad(s)… I’ll even supply my own firearm and ammunition! I’m thinking the Browning Auto-5 12-gauge with 3″ magnum deer slugs would be my first choice. Weatherby .460 Weatherby Magnum would be 2nd… The Weatherby has a ton more muzzle pressure and velosity, but the 12-gauge has a bigger shell.
I eagarly look forward to this duty!

Good review. I’m also awaiting a EZM1.
Perhaps Poljot can buy the tools and machinery from Lemania for producing the a russian version of the Lemania 5100…. Such a pity to see this movement discontinued.

I forgot to mention that I “borrowed” the “will be the first against the wall when the revolution comes” part from “The Hitchhiker’s Guide to the Galaxy”, by Douglas Adams. In the book, “The Guide” says this about the marketing division of some large company. Go figure…
The L5100 isn’t discontinued if you belong to the Swatch group ;^P
2112, can you expand on: “The L5100 isn�t discontinued if you belong to the Swatch group”?
So it will still be ijn production for Swatch companies? May I ask where you heard/read this? Just curious.
Thanks!

Ironically, my EZM.1 stopped last night
It seems an automatic winding problem. I don’t really worry as I’m quite confident that Horlogeplatform Den Haag (my watch pusher) will have it fixed by Sinn. But it’s still a crack in the Lemania 5100 legend… At the moment, my ultra-reliable Speedmaster is back on my wrist

Bas,
I don’t know that ‘fixing’ it is an issue. This is a peculiarity that crops up in a number of EZM-1’s. Some have a low power reserve, some don’t. Check the Sinn forum archive, and you’ll see many other people with this phenomenon. Winders or vigorus wear seem to be one solution.
Oddly, it ONLY appears with the EZM-1 and none of their other 5100 models (156, 142, etc.) Some suspect that it has to do with a winding rotor modification.

Chris,
The movement is owned by Swatch, and they have chosen to discontinue it. There has been some indication that they could choose in the future to use it in one of their own lines – but for competitors it is no more.
Regards,
Jeremy
Jeremy, thanks for your comments. The fact that it happens often gives me good hope that Sinn will be able to pin down the problem.

No thanks
I will not buy a winder as a workaround for a broken watch, nor will I wear my watch vigorously. That’s just ridiculous.
I have an 1969 Omega (cal 564) that just sucks energy from thin air. 4 hours of normal wear gives it 45 hours of power reserve.
Having seen this, I think that in 2004, a company like Sinn should be able to make an automatic watch that makes it through the night, period.
Disclaimer: I’ve only done one winding efficiency measurement ever on my Omega 564, but I will wear the EZM1 and the 564 together for 4 hours and then compare the reserve they collected.
very sad that the 5100 is discontinued:(.It was an excellent movement way better than the valjoux 7750 and all its derivatives. RIP Lemania 5100, gone but never forgotten.
I just got an EZM1 too – I was worried that they would be gone and I would always regret not buying one. So far, so good. It keeps great time and seems to have a normal power reserve.
I consider it the Heckler & Koch of watches. Hey, if it is good enough for the German Special Forces, it is good enough for me.
Here is another article on the EZM1 – http://www.broadarrow.net/ezm1.htm
Hmm, I just read this back, seems some update is needed even though it is rather late. The watch was sent back to Sinn and I remember it took them some weeks to fix it… I was told that the winding stem was too long, which locks the winding mechanism when you screw the crown. This did sound a bit weird to me but the watch didn’t show any power reserve problems ever since, it Just Works now.
