Important Notes
Some customers have reported that the watch may run a few seconds fast or slow per day, which is normal for mechanical movements. The bezel action might have slight backplay, but this doesn’t affect functionality. While the watch comes with a titanium bracelet, some users may want to replace it with a NATO strap for different styling options. The watch doesn’t include a user manual or warranty card in the package, so customers should contact the seller if these items are needed. Regular maintenance every 3-5 years is recommended to keep the automatic movement running optimally.
