The two tone matte exterior and polished interior were well done. In general, the mechanics were reliable. I had to remove 4 links to fit my small wrist. This meant removing four connector pins and replacing two of them. Removing the pins wasn't as easy as shown in the video, but I managed it in the end. A locking lever prevents the strap from opening accidentally, and this lever is quite tight the first few times, but soon becomes loose. If you lack patience or manual dexterity, you can entrust it to a jeweler.
