Seiko 5 Sports GMT SSK001K1 – “Black Grape A.K.A. Bruce Wayne” Black Dial Edition – Brand New Full‑Set

This is the iconic “Black Grape” A.K.A. “Bruce Wayne” Black Dial GMT from Seiko’s SKX-style GMT lineup — the SSK001K1. With its sleek black sunburst dial, subdued black-and-gray bezel, and refined red GMT hand, this watch delivers understated elegance with serious GMT utility. It's brand new, unworn, and ships as a full-set including original Seiko box, manual, hang tags, and warranty card.

Get Noticed

The deep black dial paired with a matching gray-and-black GMT bezel creates a sophisticated and versatile look. The 42.5 mm steel case and stylized five-link bracelet (~161 g) offer both presence and comfort. Powered by Seiko’s robust 4R34 GMT movement with hacking and hand-winding, and finished with LumiBrite-coated hands and markers, this watch is both practical and visually refined.

Which SSK001 Are You Getting? (J1 vs. K1 Explained)

Seiko releases the SSK001 in two official variants:

• SSK001J1 – Japan-made version: Assembled in Seiko’s Japanese facilities and typically marked “Made in Japan.” These versions usually command a premium due to origin and collectibility.

• SSK001K1 – Export version: Assembled in Seiko-owned facilities outside Japan (commonly Malaysia). It matches the J1 in movement, materials, and finishing, but is typically priced lower.

Both share:

• The same Seiko 4R34 automatic GMT movement

• The same 42.5 mm SKX-style stainless steel case

• The same black sunburst dial with red GMT hand and black/grey bezel

• The same stylized stainless steel bracelet

The only distinguishers are:

• Assembly location (Japan vs. overseas)

• Minor dial and caseback text differences

• Price (J1 usually costs more)

Neither version is “fake” or backsides inferior—both are authentic Seiko releases crafted to Seiko’s high standards.

This listing is for the brand-new, full‑set SSK001K1 export version.
