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 Ronda, 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.

Accuracy:

According to official documentation, Ronda claims that the caliber 715 has an expected “Instantaneous Rate” (accuracy) of -10 to +20 seconds per month at normal operating temperatures of 0-50 degrees Celsius (32-122 F).

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.

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 »

It’s true that there are less moving parts in a quartz watch, but there are still bearing surfaces and moving parts. The 715 made in Taiwan with Swiss parts and one jewel are of lesser quality than the 715 5 jewel made in Switzerland. The expertise of the Swiss makers and in house control are better, and the 5 jeweled surface foundations are paramount to the the overall longevity and accuracy of the movement. A jeweled bearing surface smooths out the vibration impulse at a much greater rate than non jeweled.

I’m sorry you had a bad experience, but I have 6 watches with the Rhonda 715 and every one has been a reliable, solid performer. One is in a nearly 20 year old Luminox that still keeps impeccable time.

I just bought a Nite Alpha. Because of my age I’m starting to have some vision problems. I have owned two Luminox watches in the past. They are great watches, but I had a difficult time seeing the dial at night. I have no difficulty seeing the T100 tritium Alpha dial at any time during the day or night. So far, it seems to keep excellent time (one week) when I compare it to the US Naval Observatory website. The date is located between 4 and 5 o’clock. When you bend your elbow to look at the date it is… Read more »

My Belair Seapearl 20ATM model ref. A9701 is fitted with a Ronda 715.
This is indicated with the movement number added below the ‘6’ marker on the dial next to the ref. #.
Other A9701 Belair Seapearl’s had the ETA 955.114 — a movement also used in the similarly styled A9705 titantium.

my very handsome new Hanowa Offshore Diver (20bar Sapphire crystal) Uses this movement. The brand puts a lot of emphasis on being Swiss made and carries the official Swiss Military cerification so I suspect its the fully Swiss made version. As long as it works I couldn’t care less which it is. I use the watch when I am swimming, kayaking and generally doing sea sports plus it looks really good as a dress watch – the dial is a clone of an Omega diver

I have a silver BMW quartz watch that was/is being sold at the BMW dealerships and factory branches. The official BMW parts catalog number of the watch is 311776. It proudly carries a “Swiss Movement” engraving on the case back and is waterproof at 10ATM. I opened it to see what brand the movement is and it has the Ronda R9 with 5 jewels.

How accurate is this movement? I have a Luminox Series 1570 watch that quit working. I sent it to Watch Repairs USA and now it runs slow about 1 or 2 seconds a day. Is this acceptable? Can it be adjusted? If not, should I send it back for a new movement?
