Martin:
I envy the thrill of the hunt for your first Rolex. Here are some comments.
1. The 15200 is a 34 mm watch. In the past, I have owned a sold yg and a stainless 34mm date. Great watches, but today they would be too small for me. Since this is a significant purchase, I recommend that you make every effort to try one on and compare it to a 36mm, 39 mm and larger sizes.
2. If this were to be my one and only, I would make sure to buy one with the original oyster band. If you purchase a watch on on an aftermarket strap, and later decide you want an oyster band, you will be shocked at the cost.
3. Unless the watch you buy has a documented recent service from a RSC or a reputable independent, remember to factor in the price of a service. And this can greatly affect what you should pay for a given watch.
4. As an exercise, I always compare the price of a new model that does not need a service against the price of an older model. Sometimes the closeness in price surprises you. Particularly if you factor in a service.
5. For example, as far as the 15200, I have not done a thorough search, but let's say you buy a 15200 without box and papers for $3900. And let's say you have to spend $850 for a service. You now have a used older model watch with $4750 invested. And you have no box and papers. It will not be as easy to trade this watch if you want to down the road. Now lets' look at some other options.
- The current Rolex date 115200 lists for $6,500. This comes with the newer movement, all the bells and whistles and of course a 5 year Rolex Guarantee.
- In April of this year David SW (gold standard TS) had a 115200 with full kit and still under warranty for $4675. You might call him to see if he can source you one now and at what price.
- David SW currenlty has a black dial June of 2018 239mm OP, for $5,300. Does it have a date? No. But it is stunner. And it has the balance of the 5 yr warranty. Is there room to negotiate? Don't know. But worth a call.
My point here is make sure and compare all of your options. Factor in the cost of service. An older model is not always the best value. Make some calls. You may be surprised at what you find.
Good luck and enjoy the hunt.
