Never used brand new sitting in my father’s collection all these years. Works and is in excellent condition. There is a plastic cover on the crystal to avoid scratching. You can take it off if you like. It’s protecting the actual crystal from being scratched. This vintage Chase Durer Fighter Command wristwatch is a true masterpiece. The watch, with a round shape and matte finish, has a 43mm stainless steel case material making it durable. Some of its features include a fold-over clasp, screwdown crown, and luminous hands and indexes. The watch is also water-resistant up to 100m (10 ATM) and has the digital features as well. The timepiece is a quartz movement with 23 jewels and has an analog and digital display. The watch has a stylish black dial color and a bracelet band/strap made of stainless steel. The Chase Durer Fighter Command is perfect for military and pilot/aviator enthusiasts. This item comes without seller warranty, papers, or service records, but it is in excellent working condition.
