Hands-On: H. Moser & Cie Endeavour Tourbillon


We’re looking at a very rare H. Moser & Cie Endeavour Tourbillon Fumé and the beautiful HMC 804 movement. H. Moser & Cie is one of the (few remaining) independent watchmakers out there, this means they are essentially free to do whatever they want. The great news is that they choose to use this freedom to make highly polished & great-looking watches.


The iconic fumé dial has a simple ‘H. Moser & Cie’ logo, classic applied markers & leaf-shaped hands. Funky detail, despite this watch being more Swiss Made than many Swiss Made watches out there, it isn’t mentioned on the dial. Then of course, at 6-o clock, should you not have noticed, there’s a striking & flying tourbillon at work: 


The tourbillon is essentially an interchangeable tourbillon module. True to the spirit of Moser’s escapement module philosophy, this module has been conceived with an improved service experience in mind. The module allows for an overall more streamlined service process, meaning much less waiting time. Essentially it allows the module to be assembled & regulated completely separate from the watch. At the time of servicing, the module can then be swapped out with a pre-regulated one instead of having to start from scratch at the time your watch hits the service desk. Genius.

Looking at the other side of the watch, there’s a see-through back. The movement staring back at you is the HMC 804 calibre. Moser’s movements, this one included, are handfinished & decorated, so you know this is going to be a wild ride: 


First thing (other than the tourbillon) that jumps out in a great way, is the 18-carat red gold rotor. Looking a bit closer, you will also note the skeletonised bridges for the tourbillon which add a lot of visual spice to the movement. Not visible, as they’re hard at work, are the double flat hairsprings which are manufactured in-house:


All the bells & whistles that you expect in Haute Horlogerie movement finishing are absolutely here. Most visible are the gold chatons, anglage-a-plenty and the true-to-Moser alternating wide and narrow Geneva stripes:


A closer look at the gold chatons used by H. Moser & Cie, secured in place by three screws:


And notice indeed how the Geneva stripes alternate between wide and narrow stripes, tyical on a Moser movement:


Check out the Moser teeth on the wheels which are an often overlooked yet worthy detail. You can recognize them by the round bottoms as opposed to the usual flat bottoms. Oh and I hear you thinking ‘did he just say Moser teeth?’. Yes, yes he did. In a nutshell, Moser teeth are essentially very efficient & strong teeth, so have a look:


There you have it, up close and personal with the H. Moser & Cie Endeavour Tourbillon:

  • 18K white gold case, 42mm diameter, 11.6mm high
  • Self-winding HMC 804 calibre
  • Minimum 3-day power reserve
  • Double hairspring
  • One-minute flying tourbillon




  1. Oh man, this makes me even more curious to see the full photo report from your event with H. Moser! Finally some pictures of H. Moser that aren’t 3D rendered images. It seems most of the Moser coverage is with renders and not original photography. Such a shame as they’re clearly wonderful to look at.

    I laughed at the Moser teeth bit, I hadn’t heard that before 😀

    Can we conclude this was your favorite model of the day, if you went all macro on this one?

    1. Photo report is coming I promise. Likely two Monday’s away from today, just a lot of pictures to sort through.

      Hmm, no I wouldn’t conclude that, it just happened that I had some of the best out-of-the-camera shots ready from this watch, so it made for an ‘easy’ first post covering their watches. There were quite a few that to me stood out, the Pioneer is all kinds of good (slightly large for my tiny wrists) and also attainable which is very cool. The Endeavour Perpetual Calendar with the funky Blue dial, was my absolute favorite without any doubt. Movement, dial, proportions, case, absolutely perfect. Even the date window looks good! Close second would be the Alp watch, it really is everything except boring. But yes, Brian, feel free to start a GoFundMe campaign for the Perpetual Calendar for me 😉

      1. Haha 😀 Thanks for clarifying! Now counting down for the full report, thanks a lot!

  2. Oh boy, this really makes one dream doesn’t it :O Mooi gedaan Jean! Prachtige foto’s van een al even prachtig horloge! Het heeft u duidelijk kunnen bekoren :(en terecht) 🙂 Fijn om te zien & lezen zoals altijd

    1. You would have loved it for sure amigo! It did not disappoint 🙂
      Merci & hopelijk zien we mekaar binnenkort nog eens Mr Globetrotter! Fijn om je hier te lezen by the way!

  3. WOW, I’m breathless from this mini photo review! Those macro shots are gorgeous! The hand finished stripes and the anglage are beautiful! You have re-awakened the beast for wanting a Moser and kept the flame alive! I have brushed it aside previously, but you made me put it back on! Now I’m eager and at the same time worried about the full report!

    1. Be very very afraid man 🙂 Some gorgeous stuff in there 😅 The manual wind have more details to look at and are gorgeous. I believe that once te Moser flame is lit, it burns forever… 🔥😁🥂👍

  4. Regrets… I have a few… but then again… too few to mention..
    My friend.. I’ll say it clear… I so very much regret not being able to attend this meet, oh dear….

    Looks like you guys had a blast! If this is just an appetizer of what has been served that day, please make this happen again! Can’t believe I couldn’t attend (yet again)

    1. Hah Claude, great to read from you in such a lyrical way 😀 Well, the good news is that Moser is available in your country. But yes, I know what you mean, it was a very nice day (and sunny too, how about that)! A few new ‘watch goals’ were set on that day as well if you know what I mean :-O

      I totally understand you couldn’t make it of course, consider yourself invited for the next one (hopefully it works out better for travel in that case)
