A barely worn Seiko Turtle automatic 44mm men’s watch, designed to resemble a vintage Seiko.  Model reference 4R36-04Y0 or SRP775


From the serial number on the case back we can accurately date this watch to being made in June 2018, and it was sold in December 2018.


The watch is practically perfect.  The bracelet still had some of the protective plastic on the inside which we have now removed.  The watch was designed as an update to the 6309-7040 from the 1970s and 1980s, and the overall impression is that it is an honest and worthy update.  The turtle case is a little larger, the bracelet better built and importantly the movement has been improved.  The 4R36 movement boasts upgrades that include hacking and hand winding.  There is a long term review of this model of watch on Hodinkee here, which is worth reading.  The lume on this watch is up to Seiko’s high standards, which are among the highest standards.

This watch will be supplied with the original presentation box, papers and our Certificate of Authenticity.
