Seiko 5 Sport SNZG15J1 (add more in the comments below) |
The Seiko caliber 7S36 is an automatic movement used in many popular Seiko divers and the entry level Seiko 5 watches. This movement was first released to the market in 1996. Seiko dive watches, such as the Orange Monster, have since been upgraded to the caliber NH36 (aka 4R36), making Seiko collectors happy because the 7S36 seen here does not hack and is not hand-windable – two functions that have become more and more popular. The caliber 7S36 is the last in the series.
