Arsenal, Swiss mechanical watch (serviced)

Swiss-made vintage Arsenal wristwatch. - Judging from the serial number, manufactured around 1963. - Mechanical 17 jewels movement in good condition, manual winding. Double casing design, sturdy shock-proof construction; will take some beating. - Round stainless steel case of an elegant size: Width 34 mm excluding the crown, 36.5 mm including the crown, lug-to-lug 41 mm, lug size 18 mm. - Comes with a non-original butterfly-clasp bracelet. - Serviced in 2025 and keeps reasonably accurate time for its age (please see screenshot). - There's some loss of original lume on the hands, the Arsenal logo is faded (but still legible if viewed at a certain angle), glass and case scratched but nothing that can't be fixed with a good polish.
