When it comes to the overall age of you watch, there are a few things you can look at. Lets start at the first and most visible piece of the watch, the design. Wristwatches have been around since the beginning of the 20th century, and the designs have changed a lot. From the 20’s till the 40’s the Art Deco style was the main design. Often these watches were squarish. In the 40’s this design changed and we saw a rise in round, and military watches. From the 50’s and onwards we see a lot of technological advancements in watchmaking. Watches from this era got more sporty and stylish, and offered more features. When the 60’s came around a lot of watches got designed for nautical and spacial exploration. This caused a rise in Diving watches, and Pilot watches which often featured chronographs and tachymeter functions. In the 70’s the innovation of Quartz watches was started by the brand Seiko, so if your watch is Quartz powered it is likely from the 70’s or later. From the 80’s different materials were used for cases like titanium or a plastic composite, and Plexi glass crystals got replaced by sapphire one’s. From the 2000’s and onwards we see more digital watches and bigger watch cases.
