I don't own one, so I can't speak to the COSC accuracy, but if it's marketed as COSC certified, I would think it would meet the spec.

I have seen one in person and tried it on. It's a great watch and a blue dial version had been on my list to acquire for a while (I've been looking for a previous generation Marvelight without the in-house movement).

I will say that when I tried it on, I found that it wasn't sufficiently different from my Engineer III Endurance to pull the trigger when I saw it, other than the difference in the dial color. I'm still debating whether to add one, and might still if I find a previous generation pre-owned.

It'll wear well at 40mm. There's definitely some heft to Ball watches as they are solidly built. And that tritium glow...

 

Which model is this? I'm looking for a simple Ball without the large end links that stick out past the lugs, so this model would be perfect for me.

 

I would grab one in a second of I was in that market. I just bought the moon phase Engineer II on stainless bracelet. I also have a beloved Fireman Glory.

I've owned and worked on watches of all levels. Ball will not disappoint.

I probably would have grabbed a Marvelight had I not been seeking a Ball Moon Phase.

All their movements work very well. Do your research. The BALL standardization on the RR watches lead to the COSC and other timing and sturdiness standards.

I was set on the train master, but this Engineer II is amazing.

They are great watches.

Excellent build quality and very good accuracy, like all Ball watches.

 

The previous generation blue Marvelight was my first Ball and still remains my favourite. Timekeeping has always been very good and it's just a joy to wear. Sadly, it will be moving on to a new home next year because my hands can't cope with screw-down crowns any longer, but I know I'll miss it when it's gone. Even seeing it in the watchbox can bring a smile to my face.

 

I know this is an older post, but Bergeon (and others) make tools to wind crowns. Maybe something like this would solve your problem?

I have several Ball watches and I lover them all. If you like the style of the watch you won't be disappointed. It is a beautiful watch. I've come to view the COSC rating a nice thing to have, but it may very well be some of your other watches keep better time when worn during your daily routine.

 

I'm waiting for delivery of one likely due this week or Monday. Mine has a cyclops to magnify the date which your picture doesn't show; I believe that is the case for the 43mm version. The movement is an ETA 2824-2 which is a rock solid movement and used by many manufacturers.

 

That would mean that it is not the Engineer M Marvelight. The M denotes the manufacture movement.

There are, of course, previous variations of the Marvelight which use the ETA movement, just not the model to which the OP was referring and to which he was inquiring.

 

I have had my M Marvelight for 3 weeks now and I could not be more pleased. This my first Ball watch. (Where have I been?)

One question? What does the model term Marvelight signify?

 

Marvelight refers to the large tritium indices on the face providing a large amount of light.

 

@Kivis what is the accuracy so far ?

 

Beautiful watches and very solid builds. The t100 is the best. Some of the large numbers with all the trit is hit or miss for me at times but overall a great company.

Accuracy so far is about 3 sec slow a day

 

Damned double post

 

In terms of COSC, I can't talk generally, but I have a Ball Deepquest which is COSC and the timekeeping is incredible, -3 per WEEK. This is an ETA model. I also have a Ball Fireman Racer, which isn't COSC, and that runs at about +5 day. i've been very happy with both and will most likely pick up another Ball in the future.

 

So finally I have mine :-!:-!:-!
It is absolutely marvellous !

 

Nice review:

The watch has understated elegance, you will never regret buying something this well made.

 

Great watch; how about a shot of the clasp as well? Big fan of my Marvelight (not M). I'm in the 40mm camp, fwiw.

 

Recieved mine last week, really like it so far. Running about +.04 per day.

 

Tres agreable! Portez-le bonne sante.

 

It’s exactly the same as my 41mm Engineer II Moon Phase, blue dial.

I really love the heavy bracelet, though some might see it as overkill. It actually makes me really appreciate how light and well done the Fireman’s bracelet is as well.

I love that BALL doesn’t skimp on the bracelet, case, dial,... Very few manufacturers have such consistency.

My Oyster has BALL printed in the clasp, where my Fireman has the Spherical RR. I think it might just be different per the size you chose.
40mm vs. 43mm.
I would bet the tapering bracelet has the spherical RR

I love the blue dial on the moon phase. I have seen a Marvelight “M” with blue dial yet, or is tgg HH at just because a Gnomon moved a good bit of stock this past November and December?

I have a question: I've noticed that the tip of my second hand is bend inwards (vs the dial face).
Is this normal ?!? All the Marvelight watches are like that or mine is faulty ?

Thanks for the replies.

 

I have a Ball Trainmaster. Same thing. I believe it's done to cut down on parallax.

 

No one ?!?

 

Not a normal thing. That would bug me.

I'm coming back to check-out your opinion on this: I've received the answer from Ball - It's normal to have the seconds hand bended inwards as, due to the hight of the luminecent tubes and courved saphire chrystal, the second hand will touch the chrystal !?
I find this a little bizarre.

Does your watches have the same thing ?
Please reasure me that I've not been tricked....after all this is Ball "official" answer...

 

Seems plausible to me. Otherwise they would have to make the case even thicker.

 

I've seen the same on other watches.
