    Sourcing Notes: Vertically integrated Chinese manufacturer. Founded 2016 in Zhongshan by Liao JiaMing, who personally learned case machining, dial production, and hand-fitting in the factory. Movement: Mix of Seiko NH35/NH38 (Japan), Miyota 9015 (Japan), Seagull ST2130 (China), and PT5000 (China, ETA 2824-2 clone). Higher-end pieces use Miyota 9039. 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. Assembly: Final assembly, regulation, and QC done in Zhongshan.

    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.

    China falls in the 12.5% flat Section 301 forced-labor tier (effective July 24, 2026), stacked on top of the pre-existing ~7.5% Section 301 China surcharge for mechanical wristwatches (HTS 9102.11). Exact incremental duty varies by HTS classification.

    Tariffs are assessed based on where the watch is assembled, not where individual components originate. A watch with a Japanese movement assembled in the US incurs no import duty.
