Breitling Galactic Chronograph II

ORIS Advice needed -- Shopping for a Pre-owned TT1 Diver
Well I think I have found my next must have piece. An Oris TT1 or TT1 Titan diver.Been trying to do my research on the entire lineup, but they all look so similar, esp the titan series. Not to mention older versions with slight changes make it that much harder. A few basic questions:1) What model year marked the change over from the carbon fiber looking dial to the new wave style?2) Are all the TT1's 44mm or larger?3) I know this isn't the must have piece according to the masses, like a Big Breitling or Rolex, but are there a number of replicas running around on ebay?4) How does the titanium version feel. I am used to a big heavy watch should I stick with the SS?5) What kind of prices are we typically seeing on the preowned market for an entry level non chrono 44mm TT1/Titan.6) Are all the oris watches marked with a serial number on the caseback and have a corisponding serial on the paperwork?Any insight from the Oris enthusiasts would be great, thanks.

New Tissot on the Way
Thought I'd give Tissot a try. My wife likes it when I wear chronographs, and I just love the design. Silver dial, retrograde movement, solid bracelet, sapphire crystal. I liked this one over the PRS 200 due to the better bracelet design! Any thoughts on this model??

2870 Value Question?
Is the 2870 undervalued or not? They seem to be going for only 20 - 30G (on a good day. It seems they should be in the 50-100G range. First of all they are made by AP. They are historic, being the first automatic and thinnest tourbillon made at the time. And just being a tourbillon seems like it should make it more expensive. It has been said they are difficult to work on, but so are many other watches. What am I missing in the value equation?Thank you so much for your input.

Gifting a Rolex- sizing it before they get it.
Hey guys - for anyone that's gifted a watch (like a DJII ) what did you do to try and get the size right before you gave that person the watch?Also, pretend that you can't measure their wrist as they're not physically near you. It is for a person I know very well (fiance) but she is out of town at the moment and that would be quite obvious anyway. Her Apple Watch, which I have here, doesn't show the markings of where she wears it. Just curious to see if anyone has any tips/tricks other than what the obvious and other than touch luck. Gifting it to her when she comes back this weekend.Thanks

Rolex Warranty
I've read conflicting stories on whether the 5 year factory warranty is transferable or is only valid for original owner. I don't have the original green warranty card, but was told the watch was bought new in April 2017 and has the remaining 5 year Rolex warranty. Does Rolex repair center check serial and warranty status? Any way they can verify the warranty status of my Rolex?Thanks!
