This is a rare Jaeger-LeCoultre Albatross. It is quartz-powered. There is a defect: the hands and date do not synchronize, but they can be operated. It might be a good option for those who don't mind the date function. The case is 30mm, a boy's size, but it appears larger due to the integrated bracelet and case design. The wrist size is approximately 17.5cm.
