Prime SwissTime

Prime SwissTime is a platform dedicated to the sale of vintage luxury accessories, including watches, jewelry, and handbags. Acting as a trusted curator, the brand sources exceptional pieces from collectors and individuals and offers them to buyers through a refined e-commerce experience. The goal was to create a modern, scalable platform that supports sourcing rare products and selling luxury goods while maintaining a premium, trustworthy user experience across web and mobile platforms.

Prime SwissTime needed a flexible e-commerce solution that would go beyond a traditional online store. The platform had to support two distinct interaction flows:

– buyers, who could browse and purchase curated luxury items directly from the shop using a standard cart checkout, as well as submit sourcing requests for specific products that were not yet available, and

– individual sellers, who could submit inquiries to sell their watches, jewelry, or handbags directly to Prime SwissTime for evaluation and potential acquisition.

Our task was to design an elegant web shop, develop the code, integrate it with external platform for stock management and create a new customer communication channel in the form of a mobile app in Flutter.

We designed and developed a comprehensive e-commerce platform tailored to the vintage luxury market. The Prime SwissTime website supports English, French, and German, ensuring accessibility for an international audience. The clean, user-friendly layout highlights product imagery while keeping navigation intuitive and focused on the shopping experience.

Individuals looking to sell luxury watches, jewelry, or handbags can submit a dedicated inquiry to Prime SwissTime, providing details about their item for review. Each submission is evaluated by the Prime SwissTime team before any product is accepted into the shop inventory.

Buyers can browse and purchase curated luxury items from the shop, or submit sourcing requests for specific products they are searching for. The Shop page features advanced filtering options and a “Submit Offer” functionality, allowing buyers to propose their own price rather than purchasing at a fixed rate. Once negotiations are finalized, the administrator sends a secure purchase link to complete the transaction.

To ensure accurate stock information and streamline inventory management, the platform was integrated with external portals such as Chrono24 and Ricardo.ch. Real-time integrations ensure accurate stock levels, eliminating double listings and building buyer confidence in high-value purchases.

Following the successful launch of the web platform, we also developed a dedicated mobile app for Prime SwissTime. The app was delivered very quickly as a Flutter-based wrapper, enabling fast time-to-market while extending the full e-commerce experience to mobile users, both for iOS and Android devices at the same time.

By wrapping the existing web experience within a mobile application shell, the team was able to reuse core functionalities such as product browsing, search, and checkout with minimal reengineering.

One of the biggest advantages of this approach is that it is significantly cheaper than creating a mobile app from scratch, and highly more effective than relying just on the website experience:

– there’s no need to design the whole UX/UI (the screens are based on the responsive web version).

– maintenance effort is very low, because any pricing, product, or UI updates made on the client website automatically reflect in the app.

– the client gained a new channel of communication with their customers: push notifications.

Over time, the wrapper architecture can be incrementally enhanced or partially replaced with more native components if deeper performance optimization or device-specific features become a priority.

The result is a custom e-commerce ecosystem that supports the unique workflows of the luxury resale market while delivering a seamless experience for buyers and sellers alike.
