Consider this: You would likely be better off investing the money wisely. That way, in 12 or so years when your sons are ready for the watches, you can buy a set of matching Omega watches for ALL THREE OF YOU and have even MORE MONEY left over!
For example, if you put $3,000 (the cost of two SMPs at a reasonable discount) into a safe investment at a mere 5% interest, in 12 years it will be worth over $13,000!
That will be enough for you to buy ALL THREE OF YOU new Omega watches AND have a start of a college fund! Not to mention that if you add a mere $25 a month to that investment, it will then be worth $34,000 by then.
But going with your idea. if you spend $3,000 today on two SMPs, then in 12 years, you will have two old, mint condition watches worth about $500 apiece. At that point, you have THROWN AWAY two-thirds of your money! This is easy to see... look at the used watch sites and see what 12 year old SMPs in excellent condition sell for!
Besides, by that time, they may be TIRED of seeing your old watch. Your kids might better appreciate a NEW watch--something that they relate to more--instead of you giving them the old "what was good for me back in the late 1900's ought to be good enough for you two young whipper snappers!" routine. Heck, who knows what the fashion trends of the younger generations 12 years in the future will be like? An old mechanical watch may be completely laughable to the kids of that day.
