A to tresc odpowiedzi od Longinesa na pytanie z jakiego jest okresu. Thank you for your email and interest in Longines watches. Following your request, I have the pleasure to give you here below the information I found in our old hand-written registers : The serial number 4’095’081 identifies a pocket watch in metal fitted with a Longines manually wound mechanical movement, caliber 18.69N. It was invoiced to Messrs.’ Ostersetzer, who were for many years our agent for Italy, on 05.06.1924. Hoping this information is convenient to you, I remain at your entire disposal for any additional request you may have. Best regards,
