steeldive.com is titled "STEELDIVE Exclusive Official Store" and gives a contact address in Xiao Tang Village, Jiang Gao Town, Baiyun District, Guangzhou. Founding year not confirmed: one blog says the brand "has been around since 2008 as far as I can ascertain". Also sold through AliExpress stores carrying the brand name (deal posts link a "STEELDIVE Engineer Store"), on Amazon, and in the UK through a distributor (steeldiveuk.com, run from Cardiff per a 2021 blog post). A blog reports that Addiesdive began production in the Steeldive factory and moved out in 2021, while stating the two are separate companies; a Spanish forum post claims Steeldive and San Martin watches are made by the same supplier, which is unverified. Model numbers are SD19xx; a letter suffix (SD1970C, SD1970F, SD1975N...) marks a dial/bezel/strap version.
