A rarely seen Ollech & Wajs M-4 UDT divers watch with a solid ETA automatic movement.

HOW DO WE DATE THIS WATCH?

Ollech & Wajs launched the M series watches in 2000 according to their website.  The first mention we can find of the M-4 variation with the 60 bezel is from 2004, but given that you don’t see these too often we do accept this watch may be from a different year.

CONDITION

Ollech & Wajs have an interesting history, from making the first 1000M deep sea tool watches to supplying watches to CI5 (including Bodie and Doyle in The Professionals!).  From starting in 1957 they have always been a niche company rather than one of the big boys, and this watch shows what they do best – tool watches.

This watch was certified to 200M depths, has the unidirectional bezel with 60 clicks and screw down crown as well as the flip lock extension to show that if needed this could be an essential part of a divers kit.  Powering the watch is a 24 jewel ETA 2824-2 automatic movement with quick set date which is all working well.  The case and bracelet all have signs of life as a tool watch should – it certainly has not been polished!  The worst mark is a ding to the left hand side as pointed out in the video.  While it may not be a safe queen it could provide you with something rugged in your collection that you don’t need to be too precious about.  The bracelet is quite long and our sister website, SpareLinks.com, may have extra links if required.  The bracelet has been cleaned in our ultrasonic bath.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
