Measure the accuracy of your watches today! Clockwork includes several useful features. You can store watch information, measure watch accuracy, and set your watch using a clock synchronized with atomic time. Check it out now! _MEASUREMENTS USING IMAGES_ Most other watch measurement apps require either third-party equipment or that you press a button at a specific time. Additional equipment is often expensive, and timing a button press is difficult to do precisely. Clockwork solves this by letting you take a picture of your watch and indicate the time shown in the image. We then synchronize the image capture time with atomic time before comparing it with the time shown on the watch to calculate an offset. Taking measurements over time provides a real-world view of your watch's accuracy. _GRAPHS_ Watch your measurements over time on a beautifully crafted graph. The graph shows how your watch's accuracy changes over time and offers several modes to help you understand its performance. _WHY MEASURE?_ Knowing the accuracy of your watch is interesting on its own, but it also has several practical uses. It can indicate when it is time for a service, and documented accuracy could increase resale value, especially for vintage watches. _STORE DETAILED INFORMATION_ In case of theft or accidents, it will always help to have your information stored in a secure place. _ATOMIC CLOCK, DARK MODE AND MUCH MORE!_ Clockwork includes an atomic clock in both digital and analog formats to help you set your watch as precisely as possible. Powerful settings such as Dark or Light mode, separate day and date formats, and different ways to sort your watches let you customize the app to your liking. // Appfred AS © 2026

Introducing Panerai Luminor watch dial. Luminosity is a key feature of Panerai Instruments and timepieces since ever. Panerai’s journey into luminosity started with Radiomir, self-luminous paste patented in 1916 and used in the first Panerai watch Prototype in 1935. One of the main challenges was to develop instruments that could illuminate in the dark of the sea for military purposes. The Journey continued in 1949 when Panerai applied for a new patent named ‘Luminor’ that gradually replaced Radiomir. Today Luminor is the essence of Panerai: characterized by the emblematic crown protecting device and its signature luminous dial, it represents a symbol of Italian design. Panerai stands for an exclusive Swiss manufacturing watch Brand featuring unmistakable Italian design as well as highly performing innovations closely associated to the World of the Sea. Features - Open the APP to display the Panerai Luminor dial full screen on your device. - Add the widget to your Home Screen: touch and hold the Home Screen background until the apps begin to Jiggle then select Panerai Luminor dial from the widget gallery. - Enable StandBy in iOS Settings and add the widget to view the dial while your device is charging.
