New Omega Movement Caliber 3861

Some pretty exciting news especially if you are a fan of Omega. This movement will now replace the caliber 1861 found on an Omega Speedmaster. Aesthetically there is a huge difference in the look of the movement, in my opinion it looks sturdier and bulkier.

Now for the more technical side, both movements remain largely similar but there are a few key improvements in the new movement. Caliber 3861 has 26 jewels compared to the 18 jewels on the 1861 movement. The power reserve has also increased by 2 hours, meaning the new movement will have a power reserve of 50 hours. The new movement is also resistant to magnetic fields reaching 15,000 gauss. The new movement is also master chronometer rated so the accuracy of the movement has been tested to make sure it operates within +0/+5 seconds a day.

Even though this new movement provides a lot of excitement for the Omega Speedmaster, this does not mean your current Speedmaster is now redundant. It is still a great movement and it has been in Omega Speedmasters from 1996 until 2021. The movement is now discontinued but it is for the better as this new movement is a lot more suited to the Omega Speedmaster, for the improved accuracy, power reserve and the durability as well as the magnetic resistance.

As for the new Omega Speedmaster the watch remains largely very similar to the old version. However, one notable change will be the new clasp on the Omega Speedmaster.

The price of the watch due to this new upgrade has increased a bit from the old Omega Speedmaster. The new Omega Speedmaster will now be $6,300 for the hesalite stainless steel version with the bracelet. While the sapphire crystal with stainless steel and the bracelet will be $7,150. Heading over to Omega’s page as of writing this post, it shows that they are currently out of stock. Probably due to a mass amount of people purchasing the watch in order to get their hands on the new movement.

This new movement as it has become the new standard for Omega Speedmaster, was actually released in 2019. But it was released for their Apollo 11 watches which marked the 50^th anniversary for Apollo 11 space mission. People did expect them to make this the standard for their “normal” range of the Omega Speedmaster. It has now finally become a reality which is well worth the excitement.

Aside from the steel on steel version there is also two other versions of the Omega Speedmaster with the new movement. These run a lot more expensive due to the use of precious metals on the case and bracelet of the watch. There is the Sedna gold version which goes for $34,800 and the Canopus gold version which goes for $45,300. They both come with sapphire crystal and an exhibition window to showcase the new caliber 3861 movement.
