Searched the entire web but....
I cannot seems to find the colour options of strap for the 5146G.Pardon me, but I am new here and just got my 5146G in WG and trying to see other options available in the Patek original strap that can replace the original. I have though of keeping the original and using another colour option. Unfortunately after trawling the entire www, i cannot find any weblink to see available colours.Another others with straps already changed and photo to show. Or who can link me to a url with all the colour options?Thanks in advance

The Evolution of Longines' Automatic calibers, part 3

During this time they developed more derivatives off one base movement instead of many different movements in an attempt to standardize & streamline their production. Longines was also aware that many other brands were making a wealth of profit from less expensive, but still precise, movements. The 290 series was born of this turn in thinking, and you can see it is much less decorated than the 19A serie

Anyone seen a Speedmaster like this?
cgi.ebay/ws/eBayISAPI.dll...=STRK:MEWAX:ITIf you notice the pictures, there is a silver looking ring around the hesalite crystal. I've seen many Speedmasters but this is the first. I've contacted the seller and he told me that the crystal was previously polished and the reflections changed. Does anyone have any insight on this? Any input is greatly appreciated.

Best source for dating your Omega?
Reason I ask is I've looked at two different sites, and both show different approx' manufacture dates for the same serial number, and they're about 5 years apart! Serial is 77******, and Roman Hartmann dates it as 2000/2001, while an austrailian site - clockmaker.au/rolex_serial_numbers.html - dates it as 2005/2006... Any idea as to who is correct. Watch is a Speedmaster Pro.
