Seiko DX - References, Prices and Owners' Reviews

Souvenir from my father. Discovered in a drawer 4 months ago. I had never seen it on his wrist. I shake it. It restarts. I'm going to give it a chance! Power reserve tested at 40:00. No manual winding. Quick date in French and English. By pressing the crown. A cheeky 70's look. I like it. Black sunray dial. Applied indexes. Still luminescent. A tritium dot must have fallen and the hands spread it in a circle right in the center. I inquired with Seiko customer service. They tell me it's a sea lion case m330. But there is no engraving of the animal. Mystery. A beautiful 54 year old! She's looking for a new strap. Probably leather.

Here is a 1969 SEIKO DX 6106-9010 Sea Lion M330 in all its glory. The Seiko DX meant "De Luxe", which means it was a little above the more classic "5" range. The finish was supposedly better, and the dials often more worked. Mine has a rather original sunburst sector dial because contrary to the usual (sunburst starting from the center), here the sunburst starts from the index at 12:00. This produces unusual reflections in the light. The movement is the 25-jewel 6106 with stop-seconds which is of good quality, and particularly precise in my case (-4 to +8 s/day depending on the positions). The case is well finished, but the shape immediately refers to its era. That's why I bought it, but it will not be unanimous. It's a shame, and it's a good thing, because the prices of these models are quite low, even when they are in excellent condition like this one. So, if you like it, treat yourself without breaking the bank.
