Hands-On with the Mondaine Helvetica 1 Smart Watch
About a year ago, I attended a press conference in San Francisco where Frederique Constant and Alpina announced their newly developed "Swiss Horological Smart Watch Platform". Analogue watches with health tracking capabilities that actually looked like real watches. It was an interesting concept, and a more clever reaction to the incoming "smart watch" genre than slapping a logo on a digital watch.To do this, they had teamed up with MotionX, a Silicon valley company with a lot of experience in the health tracker world. Beyond the functionality, they made sure the watch was made to last longer than typical pieces of tech. It was designed to be efficient, with a 2.5 year battery, and has a modular design where parts of the movement will be able to be upgraded for a small fee. I really liked that they made it, to some extent, have the permanence of a real watch. It's truly a shame that most smart watches will end up in landfills within a few years of their purchase.They also announced tha

Rolex and Tudor Prince value estimates
I have a couple of watches that I inherited from my grandfather, that I am looking for some ballpark value estimates on. The Rolex is a Day-Date w/ 18k gold case and band - band is the hidden clasp type. I am pretty sure it was purchased in the 80's on a vacation to Switzerland.The Tudor is stainless steel band and case. I have no idea when the Tudor was last serviced or how old it is. Tudor is manual wind.Both are in good working condition and both keep good time. I have a slip on the Rolex from when it was serviced in the late 90's. Thats about all I know off the top of my head, there may be more info on the Rolex with the box and paperwork that I have, if there is anything else that will make a difference. Pics below.And thanks in advance.On a side note, the acrylic (or whatever it is) crystal on the Tudor is in pretty rough shape as you can see below. If anybody can suggest a place to get the watch serviced and the crystal replaced I would appreciate it.

Buying Watches Here and There
Guys, Heads Up. Being new to this site and buying on EBay, I've noticed sellers describing their watches as having a few months or years left on the warranty. Do not take this as a given. Warranties sometimes are valid only for the original owner!! I am sure that some of these sellers are not even aware of this fact. So take this into account when buying, although high end watches rarely fail within the warranty period.

Weirdest watch story of 2002
An odd year. But what event takes the cake?

AP straps question
Starting to look into the ROO chronos, will be my first AP. I'm wondering what different experiences have been on buying additional straps. My thinking was to get the watch on the hornback and then get a rubber strap to go along with it. Would like to stay OEM if possible.I've searched some threads and it looks like a recommendation was to go through the APSC instead of an AD because of the markup. How do you go about doing that logistically with the SC? Any feedback one way or the other? Thanks everybody.
