Seiko 7T27-7A10 & Dugena Jungster 17 Rubis watches

Two rare watches sold together: Seiko 7T27-7A10 and Dugena Jungster. Seiko enthusiasts will recognize this rare example, which is very difficult to find, but it's here. Elegant yellow hands and two-tone dial. The upper sub-dial is a 30-minute counter when the chrono is on. The lower one counts the seconds, and the second hand on the left acts as a compass. The watch has a black strap. Ref. 7T27-7A10, with original signature. Diameter without crown 37.5 mm x 42.5 mm. The watch is running, but it sometimes stops when we set the time and press the crown back in. The right pusher sometimes gets stuck, I don't know the reason. This model varies between $500-600. A new battery is definitely needed, and possibly a visit to a watchmaker! Rare Dugena Jongster from the 80s. White fiberglass case. Thanks to this, the watch is very light. The watch is absolutely flawless: Case, strap, bezel, dial, hands, index. Red dial, stacked luminous indices. Four original interchangeable bezels (pulsations, world time, diver, tachymeter). Original white sporty Swiss strap. Original ticket. The watch is running, but does not keep time perfectly. Date is locked, but changes after the watch is running. Diameter without crown 38 mm x 42 mm. Inscription 5 ATM TESTAD on the back. A truly rare, unique collector's watch. This model varies between $250-300. A visit to a watchmaker may be necessary!
