Seikomatic-P Brown Linen

The 5106 Seikomatic-P was a late holdout within the Seikomatic branding schema, to which this particular movement had a very short production run, from roughly 67’ to 69.’ Despite this, the movement has a number of surprising features across all functional aspects of the watch. First is the spring loaded Push-Button crown by which the inner hexagonal surface is depressed to advance the date. Second is the spring-loaded instant calendar changeover at midnight, rather then the more common gradual changeover. You will never see a partially advanced day or date on this watch. Additionally, and perhaps more subtle, is the integrated automatic winding system, jeweled center wheel, and jeweled barrel arbor holes, all which contribute to the longevity of the watch and its parts. Stylistically, the 7030 Linen Dial model we have here is quite substantial; It has very stout lugs, a thick case, a beveled crystal that sits proud of the bezel and markers and hands that are broader than most. The Linen Dial is coarser than most other Seikos of the era, certainly more than the white line King Seikos that followed. Paired with the original bracelet, this is a very striking and complete piece.

This watch is quite practical for daily use, however its uniquely 60s appearance lends itself quite well among winter dress, at the office or part of a vintage ensemble. It is on the chunkier end of the spectrum however the case conforms nicely the the wirst.
