Andrew from the Philippines shared with me a few pictures of a new Seiko 5 model that was released over there. I have not seen these in Singapore yet but when I saw the pictures, the Rolex Oyster Quartz comes to my mind immediately. Next came the Explorer II. Strong resemblance there especially to the Oyster Quartz.
Here’s an Oyster Quartz that I handled some time back.
According to Andrew, this model is powered by the 4R36 movement. Here are the other variants.
