The Ronda caliber 715 is a common 3 hand Swiss quartz movement. This caliber is part of Ronda’s normtech line of movements.

Swiss Parts Vs Swiss Made:

According to the Ronda website, there are two versions of this movement: a Swiss parts version with 1 jewel and nickel plated finish, and a 5 jewel version with gold plated finish. You may see Swiss parts variations listed as being made by Harley Ronda.

Similar Calibers:

There are similar calibers to the 715 including the Ronda 712, 712, and 714. The 714 and 715 both have the date at 3:00. The 712 and 713 are essentially the same, but without the date. The 712 and 714 do not have a central seconds hand. All of these calibers use the same 371 cell battery.

There is also a longer life caliber 715Li that uses a larger CR 2016 battery cell.

Hacking Seconds:

This movement has hacking functionality, meaning that the second hand stops when the crown is pulled out to time setting position. Ronda officially calls this:

Stop-second with interruption of motor impulses.

Ronda claims that hacking the movement activates a power saving mechanism that reduces battery consumption by approximately 70%. If you are not going to wear your watch for long periods of time with a battery installed, it is recommended that you pull the crown out to save the battery and reduce unnecessary wear and tear on the movement. Keep in mind that even if you keep the watch hacked, the battery can go bad and begin to leak which may damage the watch.

Stem Removal:

To remove the stem on the caliber 715, make sure the crown is in position 1 (pressed in) and use your tool to press the stem release button located next to the small arrow on the movement.

Replacement Prices:

At the time of this post, replacement prices of around $15.95 were found online for the Swiss parts version.

Filson field watch from shinola detroit factory has argonite 715 movement. Assuming this is the ronda movement theyve renamed?

Luminox 4221ANU, 4222ANU is using the LI version that allows for 10 year lifespan. I think some armorlite isobrite series watches use them too.

The original Luminox Captain’s Field Watch (part numbers in the 1560’s) use this movement, but I noticed some very subtle differences in mine vs. the pic shown on this page. It’s still a 715, however.

To how much extent these two Ronda 715 variants can affect the performance? The 5 Jewels is more durable?

Here’s what I think and someone else is welcome to reply with a differing opinion. The 715 only has hours, minutes and seconds, the one jewel is more than enough. Other quartz movements operate just fine with no jewels. In my opinion, the difference between the two is that it comes down to marketing. What better way to distinguish between two variants than changing the appearance of the metal from cheap nickel to seemingly luxury “gold” color? 1 jewel to 5 jewels for the same movement with same functions. They need a good way to make the Swiss model stand… Read more »
