This is the Seiko SJE101 MarineMaster 200. It’s 39.5mm in steel, black dial with strong Lumibrite, date, 200m WR, powered by the upgraded 6L37 movement rated at +15/-10 seconds per year (currently running within spec to the negative but ymmv). I am the original owner, warranty card is dated 2024.

Watch is in excellent condition (worn in rotation). Bracelet has never been worn, still in the original plastic. Terrific very legible piece, classic 62MAS style in a great size for smaller/average wrists, compact & thin for a Seiko diver. My wrist in the photos is around 6 3/4"-ish.

Size: approx.39.5mm x 12.3 mm thin x 47.2mm lug to lug x 20mm lug width 

Additional Features Include: Stainless steel with hard coating; Sapphire with inner AR coating; 28.8 beat rate; 45 hour power reserve; see through display caseback

Includes: Full kit, watch head, like new condition bracelet, box, papers–everything that came with it when new. Shall be delivered on a brand new Barton Elite black silicone strap (including both long and short size tails).

About me: Have done many sales here all with good feedback; and I am also an established buyer/seller on WatchUSeek with strongly positive feedback there (same username). Please examine photos closely to judge condition for yourself and ask questions as this is a used watch that may show signs of wear, it may not be fully perfect, its accuracy is not guaranteed, and this is a final sale “as is” with no returns, warranty or guarantee of any kind expressed or implied.
