Moritz Grossman is a brand we don’t cover here a whole lot on WWR.  Not because they don’t make nice watches, or nice-looking watches, but because they generally fall outside of our mission statement of covering interesting and affordable watches.  Long-time readers will know that we will deviate from the affordable part now and again if there’s something that’s just-plain cool that comes along.  And, well, the Moritz Grossmann ATUM Hamatic flips that switch.

This is a watch that was introduced at BaselWorld 2018 as a prototype, but there are indeed plans to produce the watch, and it should be available later this year.  This is the first automatic watch that the brand has produced, and the Moritz Grossmann ATUM Hamatic does things a bit differently than you might expect.

You see, rather than a rotating weight, or rotor, they’re using a pendulum mass, or what they’re calling a hammer mechanism – hence the ‘ham’ part of the Moritz Grossmann ATUM Hamatic name.  This hammer, as it oscillates, can be seen through the caseback, and through the cutouts on the dial as well.

Frankly, the movement is the star of the show here, and looks mightily impressive.  For the rest of the watch, it’s very much a dressier piece, both with the 41mm precious metal case and the silver dial.  Pair in a classic handset, narrow Roman numbers, and a larger subseconds dial, and yeah, this is not a watch you’d be taking out in the field.

As a dressier piece, though, I like the Moritz Grossmann ATUM Hamatic.  And with the new movement, it’s sure to appeal to watch geeks as well.  Given these new steps for the brand, it’s not too surprising to see the 37,600 EUR (approx. $46,547) price tag on the piece.  Suffice to say, we won’t be getting a loaner in to test out, but nevertheless, it’s still quite a stunner, is it not?  grossmann-uhren.com

Watch Overview
  • Brand & Model: Moritz Grossmann ATUM Hamatic
  • Price: $46,547
  • Who we think it might be for: You want a luxury German dress watch, one with a unique approach to an automatic movement
  • Would I buy one for myself based on what I’ve seen? That’s simply not in the cards for this watch writer
  • If I could make one design suggestion, it would be: The dial cutouts feel almost like an afterthought in the design.  I get wanting to see the hammer, but they’re just not working for me.
  • What spoke to me the most about this watch: That movement, of course!
