Here’s a rare bird of a tool watch! \[EDIT: timestamp on last photo of series, spelling, currency, 77¢ discount LOL\] My understanding is that these watches were issued to servicemen in the artillery corps; the inscription Tg is thought to represent *Tidsgivare (“time given”, a time synchronization phrase).* Tygmästare is also a term for artillery officer, another theory for the origin of the inscription. Extremely rare to find one with a near-mint glossy dial plus intact tritium lume on indices & hands. Priced US$1,000 below the cheapest one on Chrono24 and with a nicer dial than the ones found there.  Asking US$7,777 via bank wire, will consider escrow or PayPal G&S if buyer pays fees (5% for Paypal international transactions). Free shipping within North America, would consider shipping to Europe as well. My feedback speaks for itself, buy with confidence!
