Pick your dial, bezel insert, chapter ring, strap, hands and build your own custom modded 6309!


We have included photos of some examples of color combinations that have been made in the past, however stock availability and styles change from week to week, so there is no guarantee we will have all the parts shown in the photos.


The price quoted includes any of the aluminum bezel inserts we have currently available and if you would like a ceramic bezel insert, that is an extra $5 on top of the quoted price.


Mother of Pearl  & Carbon Fiber Dials are an additional $5, Regular Seiko and Tuna dials are no extra charge.

Then write your choices of dial, bezel insert, chapter ring, hands and strap in the box at the bottom of this listing. You may browse our Mod Accessories section of the store to make your choices.

Our standard strap is black wave vented rubber shown on the watch in this listing, we also have other strap selections you may browse in our store.

We take a vintage Seiko 6309 movement and case, refurbish & clean it, then mod it with brand new 3rd party mods of your choosing. You end up with a near new looking modded Seiko. There will be the occasional, superficial flaw in the case, or crystal though we do polish these as much as possible to remove scratches. These are NOT brand new watches, so please bear that in mind. The date may be slightly worn, the crown and bezel slightly stiff, or loose. We do replace any parts on the movement that are not working at the time of refurbishing and replace them them with brand new 3rd party parts, but not all parts on this refurbished watch will be replaced if they are deemed in decent working order.

These watches will be shipped directly from our supplier in The Philippines and will take up to 2 weeks to be modded up before mailing. (Usually less, but be prepared for up to a 2 week wait). Once we have finished modding your watch, we will send a photo of the watch to make sure we have got your specs right before shipping. If you find the watch did not really turn out as you expected, we are happy to refund less a $35 modding fee.
