The Black Series Limited Editions 1965 / 1968 / 1970 Mechanical Diver's
Modern Re-interpretations.

This is a limited edition “Black Series” 300m high-beat Marinemaster, 544/600. This has the extremely hard & durable black finish DHC. Watch is original and unserviced. This model features long-lasting bright Green Lumibrite Pro on the hour, minute, and seconds hands and the indexes. The lume shines a vivid green wherever you are, even in the darkest places. The black dial keeps reflection to a minimum, ensuring the highest level of legibility.

• This limited-edition is serial numbered 544/600

• Watch is a one-owner trade-in

• There are minor signs of wear apart from below:

• Watch has a brand-new NOS rotating ring installed. The original rotating ring was warped. There are two tool marks on the edge of the case between the case and rotating ring at the 3 o’clock from a case knife (see photos). They aren’t really visible.

• Movement is in good unserviced running condition, with amplitudes in the 230s up to the 260s, with .03-.04 beat error, -6-18 s/d give or take. The watch really hasn’t been worn a lot; it needs to be worn. I have not adjusted or timed this watch.

• Watch hand winds, hacks, automatically winds, and adjusts correctly.

• Comes with inner & outer boxes, rubber strap, warranty booklet, and watch usage guide.

• No returns; all sales final.
