something different this time .... Marine Chronometer
99.9% of our posts are about wristwatches but I always wanted something extra ... not for the wrist but for the house this time. Something like a JLC Atmos was an option but a big wooden box with a Marine chronometer clock inside was also an idea.
An Atmos could have been a problem because our cat ( 10K British shorthair ) is not very elegant and there is a big change he would kick it of the closet 
So maybe a Marine Chronometer clock on a table would be safer
So this is what I got
A Girard Perregaux John Harrison ( Nr7). I believe they made these from 1993 until ???
1993 because exactly 300 years earlier Mr John Harrison was born. John Harrison was the inventor of the chronometer
So here it is
with a Patek 5131 just to show the size
The power reserve is a bit more than 2 days, then you have to wind it with the key
The movement is something they got from Poljot and as you can see this will survive the next millennium, this is built like a tank
Ever seen a bigger balance wheel ?
and what about the spring ?
I think you can use it as a car shock absorber LOL
To make it more interesting .... a fusee chain mechanism
It 'ticks' VERY' loud but only 7200 beats per hour so somehow it sounds relaxing

Looking forward to learn more about this one!
I am sure it was not a big number of these made. Best Blomman
Nice catch Bruno...
I love the marine desk Chronometre. Wonderful shots and post ! Well done ! Ovi
Very nice! btw ...
... the Poljot marine chronometer movement was a copy of a Ulysse Nardin movement, possibly the best renown Swiss marine chronometer movement. Marcus
thanks!
I knew those Russians ' borrowed' the plans to copy this movement but I did not know the original was made by UN
Great chronometer,
I have always been looking for a new one, was it easy to find? Enjoy this very special piece.
it has a nice story
My AD was a GP dealer many, many years ago Somehow he never sold this one and kept it for ever in stock. Don't know if he wanted to keep it himself or not but I knew he had it. About 2 or 3 years ago he showed me this piece. I see him pretty often because...
It is funny to see that many watch fans are also loving these "montres de pont"
I also have a soft spot for them when looking for instance at auction catalogues. Accuracy standard, decoration object... so much to love. Thanks for sharing yours and congratulations Bruno. Cheers, Mark
Wow that is beautiful....
Please post as many pics as you can. How is the time keeping of it..? Given the history of the original I would assume it keeps pretty good time. Fabulous piece, Andy.
