Deadstock Seiko Jumbo Chronograph 6138-3000





The unmistakable 6138-3000 earns its well-deserved nickname, "Jumbo," thanks to its 42mm size. However, its size perfectly matches its sophistication. The matte black multilevel dial is adorned with sleek contrasting markers and skillfully framed by the subtly angled chapter. The white hour and minute baton-style hands seamlessly complement the design, while the vibrant yellow chronograph hands provide a tasteful burst of color.


The meticulously detailed case is nothing short of impressive and exudes an undeniable presence on the wrist. The bracelet, also utilized by the 6138-800X Baby Panda models, not only offers comfort but also adds a polished touch to the overall appearance. With the convenience of independent day and date quickset functions and the option to manually wind the mainspring, the 6138 surpasses its predecessor with clear advantages. 


Clean examples do not come on the market very often, but this one we have to offer is a 10/10 unused example. With virtually no scratch on the case and still retaining the original case-back's protective film and the clasp sticker, it's definitely one of the best examples we've ever witnessed, and experiencing this example in the flesh is mind-blowing.


Due to its unused condition, it will be sold as-is and all the watch features work smoothly.


We can also service it for an extra charge. Please let us know if you wish to service it.
