I like making custom 6105s, and this is the 7th “Super 6105” I’ve made. I build these slowly as random or orphaned parts come in, sometimes over many years. They’re meant to be worry-free daily wear watches, not safe queens. Besides the KVW Type II crystal, every part is genuine Seiko.

• Movement is a custom-built Seiko 6319, with two diafix settings in the train bridge, and both upper & lower mainspring arbor jewels, and a 6306 hacking lever. A feature of my “Super 6105” builds, I choose these higher-grade movements from the 6309 family based on condition and quality. Fully serviced by me like two months ago. I personally wrist-tested this watch for a week.

• Original 6105 dial and hands, relumed by IWW / Jack Thayer like a decade ago. Beautifully done, stock look, with a steady & even glow. Readable easily at night.

• Original Seiko chapter ring

• Original 6105-811x asymmetric cushion case. No corrosion or pitting. All sealing surfaces are intact. Case brushing is intact with signs of use and wear, but no abuse.

• Crystal retaining ring / bezel is NOS Seiko

• Crystal is one of our KVW Type II Hardlex crystals, the most commonly used 6105 crystal. Only produced by us.

• Insert is genuine Seiko 6105. Original pip is relumed to match the dial hands. Insert saw a hard working life. It was touched up with a durable black enamel.

• Rotating ring is a genuine Seiko from a 6119 Rally diver. It turns smoothly and silkily.

• Crown & stem are genuine Seiko. Crown has been rebuilt with a new gasket.

• Locking pin is good - crown locks as it should.

• Caseback is genuine Seiko, modified / sterilized by Jonathan Koch / Swedefreak of EastTech - the granddaddy of all vintage Seiko collecting. He was a good friend, mentor, and partner.

• Watch comes with a brand-new Uncle Seiko 19mm “waffle” strap, and a brand-new Uncle Seiko 6105 H-link kit with solid-stainless bracelet, solid endlinks, and genuine Seiko “fat” bars.
