Thanks in advance for you advice. I have started collecting only recently and my collection is really only a Rolex Datejust from the 1990s an old Olympic from the 1940s. Now, I wish to buy a very good chronograph. I like chronographs but I also need one for my job for at least the next 2.5 years. The job requires basic chronograph functions and I need the chronograph to have a tachometer and a telemeter. OK so I saw Baume & Mercier Men's 10001 Capeland Chronograph Black Chronograph Dial Watch. These are featured at Amazon for $3K with a good lay away option. I read some reviews about Baume & Mercier and at first they were great but soon I uncovered so comments to the effect that if you have $3K to spend on a chronograph it would not be Baume and Mercier. But please let me know. If not Baume and Mercier which chronos should I be looking for at $3K? Small note I insist on a leather band. Second recommendation: are there 300-500 dollar class chronos that I should consider because I might beat up my watch in my job in the next couple of years. Citizen? Seiko? Please advise.
