Prepares an order of this configured watch for the user. ONLY call it when the user explicitly asked you to order it and agreed to share their name, email and delivery address with B.R.M (user_consent=true). B.R.M then emails the user a summary with a 'Confirm my order' button; the order is placed ONLY after the user confirms it there (link valid 72 h), choosing card, interest-free instalments (Alma under EUR 2,000, Pledg from EUR 2,000, where available), a 30% deposit (watch from EUR 3,000) or bank transfer (EUR only), and pays B.R.M himself on B.R.M's secure payment page — no card or bank details go through this tool, and you never pay or commit the user. Relay message_for_user to the user. Do NOT say the order is placed, do NOT ask for payment details, NEVER promise a delivery date. The price is computed by B.R.M for the delivery country (currency and VAT follow the delivery country). Limited to a few orders per day per email. Pass an idempotency_key to make retries safe.
