hi folks, i was talking watches to my son this afternoon. i showed him my Reverso Grande GMT and told him that this watch has 8 days power-reserve because it has 2-barrels running inside. then, he asked how do these 2 barrels run? they both run independen... 

indicate and inquisitive and strong thought process for his age. I wish I could help but I am clueless too.

hi Arthur, my son read your reply, he smiled and said "thank you for your kind compliment." stefan

Hi Stefan, hi Stefan's son! I know of three different reasons to put two barrels into a watch: You need a lot of torque for driving something big.

Hi Stefan, hi Stefan's son! D..., I always mix up the "Insert" button and the "Igame uploader" link.............. Sorry for the first post. So here we go again: Basically I know of three reasons to put two (or more) barrels into a watch: 1. You want to dr...  

this is why I like this forum! It would be great if "technical" posts like this could be grouped into a sticky thread or a wiki area for future reference - or is there one already? stitch

for such a detailed explanation.... Cheers

three barrel watches work the same way? Cheers

go by the same principles as a set of two. However combinations of the things said about two barrels could theoretically be used with three or more. However I do not know about any example where this was done in reality. If anybody does I would be glad to... 

I hope, my friend, that you are enjoying your Sunday..... Cheers

but I am enjoying my spare time with indoor acvities nevertheless. I hope you do also. If it gets too bad outside you can still listen to your ding-ding-thing ;-) Best, Martin

I just finished my run outside.... rain, cold and I enjoyed it..... Now I am going to relax....if my kids let me do so ... Cheers

I had the feeling you have something you haven t revealed yet........Or Have I missed something lately???Too many clues...does it ring???PM if you want...Yours,Mo.

There is something.... and a photo was posted but at the end of a long thread...... As you understood... there are clues.... I am preparing a post..... Cheers ps pm sent

for this clear explanation.Sometimes we talk a lot about things we know little about.This is the beauty of sharing.Yours,Mo.

hi Martin, thank you so much indeed for the excellent note with very self-explanatory drawings. since i have posted the questions to this forum, my son asked me any people responded to our post so far. you know we have been waiting for such well-written a... 

Our passion sometimes can be a lonesome one (that's why we meet in this forum, right?) and so I like it very much if someone not deep into watches is asking questions. We cannot leave them alone with their questions. In this case your son asked and I am v... 

Thanks for the continued explanation. I was going to ask what the relationship was between a barrel and a spring, but I think you have answered it. Is it correct that each barrel contains its own spring, thus is an individual reserve of power? --Sancerre

Martin, thanks very much for the detailed reply. my son just started learning physics subject in his school, he is interested in your reply. he needs to take some time for him to digest this a bit more. he won't answer more question for now. in any case, ... 

I think a link to this post should be placed on HoMe for the general benefit of those of us not so fully conversant with the mechanics of our beloved watches. Thanks Nikolaj

Much appreciated, my friend. As per Nikolaj's suggestion, I will save your post in our new blog post, if you don't mind. Best, Martin. Nicolas

I love your explanation and drawings. Your post was very informative. I appreciate all the time you took in creating these examples for all of us to enjoy. Cheers, Daos

so much from most of you that I gladly grab my chances to give back as much as I can. If I only had more oppertunities to meet you gals and guys in person! Best, Martin

Very nice of you to explain it so clearly! Last week I was searching for some material on caliber 878. Although there is not much available I found the following illustration. It shows very nicely how the barrels are placed and connected. Caliber 878 illu...  

i didn't know we can play watchmaking game in LeClub. should try it out soon. thanks, stefan
