Analog Watch Crown Alarm Module for Hidden Theft Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft devices for luxury analogue watches are incompatible due to their impact on the watch's aesthetics and functionality, and irreversible modifications are not acceptable to preserve authenticity.
Innovation Solution
A hidden, reversible alarm and geolocation system integrated into the watch using a supporting and containing element that attaches to existing components like the crown, clasp, or bracelet link, utilizing short-range and long-range communication modules to detect theft and send alerts to authorized parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external anti-theft devices are attached to the wristwatch, then theft detection capability is improved, but the appearance and aesthetics of the watch deteriorate
Solution Approach 1:
The alarm device is nested within the internal structure of the wristwatch, specifically housed within the crown assembly. This allows the electronic components (communications module, accelerometer, GPS) to be concealed inside the existing watch structure, making them invisible while maintaining the watch's original appearance and aesthetics.
Solution Approach 2:
The crown assembly serves as an intermediary structure that houses the alarm device components. By using the existing crown as a container, the invention integrates the electronic components without adding external attachments, thus preserving the watch's appearance while enabling theft detection functionality.
2Reliability
If electronic components are integrated into the wristwatch structure, then theft detection capability is improved, but the authenticity and value of the watch deteriorate
Solution Approach 1:
The alarm device is designed as a separate, self-contained module housed within the crown assembly. This segmentation allows the electronic components to be independently removable without affecting the main watch structure. The crown assembly can be detached and replaced with an original crown, thereby restoring the watch's authenticity while preserving the theft detection capability when needed.
Solution Approach 2:
The system allows dynamic configuration where the crown assembly containing the alarm device can be installed or removed based on the owner's needs. When the watch is not being worn, the modified crown can be removed and replaced with an original crown to maintain authenticity for storage or resale purposes.
3Ease of operation
If the alarm device is made visible or externally attached, then ease of verification is improved, but the authenticity and aesthetics of the watch deteriorate
Solution Approach 1:
The system includes an authorized application that enables self-verification of the alarm device's presence and functionality. The application can detect and verify the unique identifier transmitted by the communications module, allowing the owner to confirm the device is active without visual inspection. This eliminates the need for visible indicators while maintaining ease of verification through software-based authentication.

AI summary
The present invention concerns an alarm and geolocation system for analogue watches, comprising an alarm device which includes a short range communications module, a processor and an energy storage device, housed in a supporting and containing element which can be fixed permanently to the watch, and a reference device with a short range communications module configured to communicate with the short range communications module of the alarm device, wherein the processor is programmed to calculate, based on at least one parameter of a signal sent by the short range module of the alarm device, the distance (D) between the alarm device and the reference device, and to switch the state of the alarm device as a function of said distance (D).
