Seiko Actus 6306-7010

An acquisition during GCQ was this Seiko Actus. While most Actus I have seen have been Seiko 5's, this one doesn't have the familiar 5 logo. It took about twice the time from before the lockdown for this watch to be delivered but it was all worth it. This is a Japan Domestic Model (JDM) using a movement that was used for Seiko's divers watches.

The watch has day and date features and not so common Hindu-Arabic numerals for the hour markers. The day wheel is in Kanji and English.

The obligatory wrist shot. I got the watch without any strap or bracelet. Fortunately, I had some extra straps and they were perfect for the watch.

The watch is powered by a Cal. 6306 that is of similar line as the 6309. These were used in Seiko's divers in the 1970s. I couldn't find the general specs for the 6306 but it likely ran at 21,600 A/h. Here is a nice link on an article about the movement - https://adventuresinamateurwatchfettling.com/2018/09/02/seiko-6306-7001/
