Case: Machined in-house in Guangdong from 316L stainless steel, titanium, or bronze (CuSn8). Dial: Produced in-house at the Zhongshan facility. Crystal: Sapphire with AR coating across the catalog.

Cost Transparency
Ships from Zhongshan, China
We don't have a verified US import tariff rate on file for this origin yet. Tariffs are assessed based on where the watch is assembled — not where individual components originate.
Ships from Zhongshan, China. Mechanical wristwatches fall under HTS 9102.21 (base duty ~$0.51/movement + 6.4% on case + 4.4% on strap). Critically, Section 301 tariffs add a 25% surcharge on Chinese-origin watches, and recent Section 122 reciprocal tariff actions may add further duties. The buyer is responsible for all import duties and brokerage fees at delivery — San Martin does not absorb these costs. Expect total landed cost in the US to be roughly 30–40% above sticker price after duties, fees, and shipping.
