Hi Jacek,
I'm sorry to read of your misfortune.
At the time of writing this there are 3 replies.
basically 1, says. "hard luck - All Omegas are like this" - I posted a few words to my opinion of this reply.
2, says we've heard a few reports of this happening recently - take it back
3, says it was a freak case, these things don't usually happen with Omegas.
I think 2 & 3 are painting a realistic picture.
You've purchased a highly sophisticated, tiny machine that you wear on your wrist. The tolerances for the parts for this machine are not measured in mm, they are measured in 1000ths of mm.
I have no idea how many moving parts are in an 1120 movement but lets just say its "a few". If just one of these is not perfect it COULD lead to problems.
From your description of your use ( more like care ) of the watch, no blame can be laid at your door.
The "Bond" Seamaster is one of Omegas biggest sellers ( now & of ALL time ). I think you have just had bad luck. If all , most or even a noticable percentage of the 1120 movements had a problem we would have read about it a long time ago.
A watch doesn't become a best seller , in one of the worlds largest & most respected watch manufacturers, without being good.
As John says take the watch back. You've paid good money for a good watch. You have a guarantee & the AD has the backing of the Omega. There shouldn't be any problem getting the watch swapped for another. Frankly after 2 weeks I wouldn't accept anything other than a replacement. Again, as John says, this should be no problem for the AD.
I have a number of Omegas. I have a 7 year old son & tiled floors.......
We still talk & my watches still run. I swim in some of my watches. I Ski/snowboard in some & I've driven racing cars in some. I also sleep wearing a watch ( no let's not go any further in that direction.... ).
I remove my watch bascially in the following situations. Showering / Bathroom, Washing dishes/cars with soapy water, Working on cars, working on the house.
Whilst I'm sure I COULD leave the watch on whilst swapping a clutch or mixing concrete, I'd prefer not to damage the watch ( ie scratch or get concrete on it ).
The Omegas that I own ( & yours too ) belong to some of the most robust watches that you can buy.
Take it back & get a new one. Then enjoy it happily for the next 40 years.
That's my advice
S.
