Orient Caliber F6724

The Orient caliber F6724 is a self-winding automatic movement with 22 jewels. This movement is found primarily in the Bambino line of Orient watches. Announcements of models with this movement were found as far back as 2016. Orient makes their movements in-house in Japan.

You may have seen this movement incorrectly listed as caliber F67-24 or F.6724, but Orient officially writes the caliber number as F6724.

F6724 VS 48743:

According to Orient, the caliber F6724 is an upgrade to the caliber 48743. Orient calls the 48743 a workhorse movement and says that the F6724 succeeds it. The F6724 offers hacking and hand-winding, the 48743 does not have these desirable features.

In a press-release dated 4/25/17, Orient Watch USA mentioned that the F6724 is becoming the standard for their premium watch collection:

“Like many of our recent releases, the Nami is powered by one of our latest mechanical movements, the caliber F6724. The F6724 is a 22-jeweled automatic, manual-winding, and hacking movement, which is slowly becoming the standard for our premium watch collection.” –Orient (Source: https://www.orientwatchusa.com/blogs/orient-blog/introducing-nami-diver-collection)

Note: The press-release quoted above may have an error by Orient. The Nami appears to contain the caliber F6722, not the F6724 featured on this page.

The newer caliber F6724 is the movement that powers 2nd generation Bambino watches (except for the open heart and small seconds models). The previous caliber 48743 powers the 1st generation Bambino. A quick way to tell the difference between Bambino generations is the text on the dial: 2nd Gen dials read Water Resistant. 1st Gen reads Water Resist.

Tip: It appears that the dial on the Orient Nami diver still says Water Resist even if it has the F6724 inside. Also, some sellers may be selling a first or second gen Bambino but using older or newer stock photos (many sellers actually don’t have a clue about the generation/version differences), so if you’re specifically looking for watches with the F6724, you may want to confirm beforehand.

Power Reserve:

The Orient caliber F6724 has a power reserve of 40 or more hours. Winding the crown 30 times will wind the spring fully and achieve full power reserve. Please report your power reserve experience below.

Setting the date:

Avoid setting the date on your F6724 watch within the hours of 8:00pm to 4:00am.

In Orient Watch USA’s own words:

“…The watch has been upgraded with the F6724 movement, a sibling of the F6922 which debuted with our summer diver watches. The F6724 movement is automatic, hand-winding, and hacking. Additionally, it is a date-only caliber, aligning perfectly with the design, and succeeding the workhorse 48743 movement.” -8/17/16 (Source: https://www.orientwatchusa.com/blogs/orient-blog/fresh-fall-2nd-generation-ac00-version-1)
