The “regular” timekeeping hands of an integrated chronograph are independent of the chronograph gearing-in other words, the hands are attached to the wheels directly driven from the base movement. A pinion is attached to the seconds wheel (the wheel that is normally paired to the seconds hand) of the base movement, and as a result the whole movement is controlled through that (as opposed to the chronograph being engaged via the fourth wheel, which is, as I noted above, how an integrated chronograph works). Here, the base movement is fully assembled first, and then the module is connected to the dial side. The modular approach is not too dissimilar from the integrated one, but it takes a more indirect route to get there. Duboid Depraz module chronograph shown here with the top plate removed. The Dubois Depraz module has been mostly used with ETA calibers by Omega and Breitling, but it’s also seen limited action inside the Audemars Piguet Royal Oak and even some Richard Mille models. Then there is the ETA 2894-2, which is essentially a 2892 paired with a module. There is the module from Dubois Depraz, which can be mounted on any automatic base movement. There are two main chronograph modules on the market today. Finally, I add the automatic winding components and the oscillating weight. This rocks back and forth to engage the chronograph seconds wheel when actuated. When that’s all cleared, I then turn to putting the chronograph components into place, which are connected to the base movement via the pinion running from the fourth wheel of the movement. I usually check timing at this point to make sure there are no issues there. When I put one of these together, I first assemble the base movement (hours, minutes, and seconds). Let’s take a look at the Valjoux 7750, one of the most ubiquitous chronograph calibers currently on the market. But is one better than the other? Let’s examine more closely. Modular systems have been used by Omega, Breitling, Audemars Piguet and even Richard Mille, just to name a few. It’s quite a clever idea, and I’m not the only one who thinks so. For example, a module can be attached to an ETA 2892, transforming it into a chronograph. The chronograph complication on this type of movement is an independent unit that is attached to a previously existing base caliber. 863.Ī modular chronograph is an entirely different beast. A classic integrated chronograph-Omega’s cal. An integrated chronograph is basically what it sounds like-the chronograph complication is built into the base movement and the two are designed to work together. Over the last couple of decades, there have been two main types of chronographs: the integrated chronograph and the modular chronograph. One of the questions I often see asked is, are all chronographs created equal, and more specifically, what is the difference between an integrated chronograph and a modular one? That’ll be the primary focus of today’s article. Today, we’re looking at integrated versus modular chronographs, but if there is something else you want Ashton to delve into, then send us your inquiry to and we will consider it for the next installment.Īs a watchmaker, I’ve seen it all-the good, the bad, and the ugly-when it comes to chronographs. So we’ve brought onboard Ashton Tracy, a seasoned watchmaker, to kick off a new series we’re calling Watchmaker’s Bench to explore some common questions, misconceptions, and ideas about watches. As long as it's different from the setpoint you will not see 68 unless you press the up or down button once to see the set point.Watches can be, well, complicated, and not all of the information out there is always accurate or reliable. The thermostat will display the actual room temperature and say Room below the temperature. When you are done, press the run program button. Do this on every thermostat in the house. Press the wake button Press the day button to set it for Monday Press the time button and set it for 6:00 AM Set the temperature to 68 degrees Press the away button Press the day button to make sure it's set for Monday Set the time for 10:00AM Set the temperature to 68 degrees Press the return button Press the day button to set it for Monday Press the time button to set it for 5:00 PM Set the temperature to 68 degrees Press the Sleep button Press the day button to set it for Monday Set the time for 10:00 PM Set the temperature for 68 degrees Repeat this for every day of the week or use the copy function spelled out in the manual. Program the thermostats to be 68 all the time.
