Sourcing Process
We specialize in sourcing rare and exclusive timepieces that align with your preferences, lifestyle, and collecting goals—whether you’re acquiring for investment, adding a personal grail, or simply exploring something new.
To begin, we ask for a 10% fully refundable deposit to secure your request and activate our sourcing process. Once received, our team of industry experts gets to work leveraging a global network of trusted dealers and collectors to locate a piece that meets your specifications and your budget.
Most requests are fulfilled within 24 to 72 hours, though rare or highly sought-after models may take up to 7 days. Once we present an option that aligns with your request, you'll receive full details and pricing. Upon your approval, the remaining balance is collected and your watch is delivered, often within days.
We make every effort to match your preferences; brand, model, year, dial, condition, box, papers, and price, with precision and care. If we can’t find a piece that meets your expectations within 7 calendar days, your deposit is returned in full, no questions asked.
Please note: The price shown on the product page reflects the most recent sale of that model through our platform and may not reflect current market conditions. Final pricing is based on availability, condition, provenance, and current market demand.
You will receive a clear, confirmed quote before any remaining balance is charged.
