Singapore luxury watch-strap brand Delugs sells across the US, Middle East, Hong Kong and other markets, with the US contributing more than 40% of business. A Shopify case study reports a 58% year-over-year increase in checkout conversion, 14% growth in returning customers and 13% growth in total orders after the upgrade. Its mechanism combines a Watch Finder for model compatibility, localized pricing, currency and duties, broader payment options, and a dedicated B2B portal for retail partners. Automated first-order emails catch sizing mistakes before fulfillment and reduce return loss. Costs and risks include high-SKU compatibility, duties, payment fraud, returns and platform dependence; the figures are also vendor-published.
