THE OTHER VINTAGE SEIKO GMT

Post by koimaster » November 30th 2020, 7:22pm

We’ve briefly discussed the Seiko Navigator Timer but what about another OG Seiko GMT watch? Perhaps you haven’t even heard of this bad boy but it is certainly worth a mention. Moreover, it is really a testament to the diversity of Seiko’s offerings in the 1970s. The Seiko Duotime.

The Seiko Duotime was produced in the early 1970s for a very short period between 1972 and 1974. It used the Caliber 5619A – the same 56 that is famously shared with King Seiko, Grand Seiko, Seiko chronometers, and the Lord Matic line. We should note, however, that it only appeared in Seiko catalogs as of 1973. The Seiko Cal. 5619A had 23 jewels, a 46-hour power reserve, and a 21,600 bph rate. A reliable automatic movement with hacking seconds and quick-set date.

With the lilt of Irish laughter

Every day and in every way

Now forever and ever after."
