Minute hand would shudder back and forth
January 28, 2012

A friend of mine bought this watch because of the excellent reviews and I intended to buy it too. Took him a few months to notice that the minute hand would shudder back and forth sporadically when the second hand is moving. He thought this was a fluke and returned it for repair. Despite the fact that the whole movement was changed, it started doing the same thing as before! Very disappointing. I can't explain why everyone has given this watch great reviews...I am being told, that It is a very accurate watch, though...I decided not to buy it, as I already read a similar review about M1 too!

Pros: Performance, very accurate, Cons: Bad design, minute hand would shudder back and forth

Great Watch!
November 04, 2006

Although I have only had the M50-MSS for a little over two weeks, I think this is by far the best watch I have ever owned. The watch is easy to read, both during the day and at night. The watch is well built and very easy on the eyes. All in all, this is a quality watch.

A superb dive watch!
September 17, 2006

The M50-DSS is a uniquely beautiful dive watch that is rugged and low-maintenance. St. Moritz makes outstanding products. I own several of their watches, including automatic, handwind and quartz models, but this new long-life battery is a genuine breakthrough--no more getting stranded with a dead watch: over ten years of steady function, a person has time to plan for convenient replacement service. Highly recommended!

in the description for the case it does not say what size it is

Superb Watch !
August 09, 2006

This watch looks like it should cost a lot more. It looks great, and for a piece as heavy as this, you don't notice the weight because the strap is so comfortable. I like the rotating ring timer feature, use it for all sorts of things. Have worn it in seawater, and wear it in the shower, never have to worry about leaks. The magnified date is great too. Highly recommended.

very impresive watch
September 15, 2006

The watch is amazing. From the time i laied eyes onto it i was hooked. It has amazing preformance specs and just as good synthetics. I got mine with the st st bracelet. The watch has a great weight and an attractable diameter. (Its not a small wimpy watch) I would defenetly recomend this watch but concider the swiss army 500m dive professional. Its basically the same with an aditional $300. e-mail me if you have any questions or concerns.

Over Three Years
May 07, 2009

I have owned this watch for over three years and worn it every day. I work in yard, hit it against many things by accident. Not one scratch on it. It runs perfect. Even the high rise date viewer, not a scratch. I do a lot of diving and this is one of the best watches I have ever had, I put it up against Omega dive any day. Nice size for viewing under water.
