Custom Watch Concepts is a German vertically integrated independent e-commerce store selling high-end sapphire transparent case backs compatible with watches from brands such as ROLEX, TUDOR, OMEGA, ZENITH, and BREITLING. Its main selling point is allowing users to view the movement through a transparent case back while retaining a stainless steel structure, sapphire crystal, and relatively high water-resistance and acid-resistance specifications.
Based on the product pages, the platform is segmented by brand and series, such as Rolex Submariner, GMT Master, Explorer, Daytona, and Omega Speedmaster. Most pages provide parameters such as compatible reference numbers, material, diameter, height, and whether the part works with Rolex case-opening tools, making it easier for repair shops or modification enthusiasts to assess compatibility. The products are mainly made from Stainless Steel and Sapphire Crystal, with DLC black coating available for some models, and are rated for 1000ft / 300m / 30 ATM water resistance and acid resistance.
Pricing is fairly straightforward: Rolex-compatible case backs mostly start from €169, some Daytona models start from €189, and Omega Speedmaster-related models are priced at €139. Listed prices include 19% VAT but exclude shipping, while DLC black coating costs an additional €89. Shipping within Germany costs €6.90, while international shipping ranges from €12.90 to €18.90 depending on the region. The site states that it ships worldwide and includes China among the supported delivery countries. Delivery within Germany takes about 3–5 days, while overseas delivery is described in different places as 5–14 days and 8–21 days, so this should be confirmed before placing an order.
The advantages are that the product category is highly focused, model coverage is detailed, and specifications are transparent, making it suitable for professional buyers with a specific watch model in mind. Payment options include bank transfer, PayPal, credit cards, and more, so the barrier to cross-border purchasing is relatively low. The drawbacks are that the site feels somewhat traditional and lacks installation guidance, detailed after-sales policies, a compatibility confirmation process, and explanations of modification risks. Transparent case backs are non-OEM compatible parts and may affect the original factory warranty, water-resistance liability, or collectible value, so users need to assess these risks themselves.
It is better suited to mechanical watch enthusiasts, independent repair/modification studios, and collectors who want to display the movement. It is not suitable for ordinary users without installation experience to operate on their own. The site lists China as a supported shipping destination, but it does not provide a Chinese interface, RMB pricing, or verified information on access from mainland China, so its accessibility should be considered unknown.
