Hamilton Introduces the Jazzmaster Chrono



Once I came across Hamilton’s Jazzmaster line, I was hooked pretty quickly (see here and here).  Well, I recently came across a new model they’ve added to the line, a chronogragph to celebrate their 120 year anniverary.

Now, if you’re familiar with the Jazzmaster line, you’ll recognize the clean lines of the case.  The 42mm stainless steel case has 22mm lugs, features a sapphire crystal, and has a water resistance rating of 100 meters.  Of course, the big design change would be the chronograph complication being added.

For the case, that means pushers flanking the crown, that look to me almost like a rounded (and oversize) crown guard.  The dial itself also has some changes, with the inclusion of a ‘Clous de Paris’ texture showing up.

Now, if you really dig into the guts of the piece, you’ll find Hamilton’s H-21 automatic movement, which has a 60 hour power reserve.  The movement is actually based off of the Valjoux 7750, with three key modifications:

  • The spiral has been glittered to increase accuracy and stability
  • The mainspring is longer to increase power reserve up to 60 hours.
  • The automatic device bridge has been personalized with a unique H pattern.

If you want to read more about the piece, you can head to Hamilton’s mini-site, or head here to pick out your own example.  While I can’t find exact pricing on this new model, the previous chrono iteration looks like it’s coming in a bit under $900.


  1. The projected price of $900 makes a bargain for an ETA 7750 based watch. Hamilton continues to provide good value. I think the watch is competently styled, but is nothing exceptional in the department. Decent looking, but conventional enough to not stand out. Sure looks thick in the side view…
