Patek Philippe "Advanced Research" Ref. 5550P Watch Uses Lots of Silicon
Silicon for the win! The material that has had watch brands debating and experimenting is here to stay and Patek Philippe is making sure of that. News from the big guys in Switzerland says that they intend for all Patek Philippe watches in the future to have Silinvar (their type of silicon) parts. A new limited edition watch called the ref. 5550P uses the brand's newest Silinvar component called the GyromaxSi balance wheel. This balance wheel has a new shape that looks less like a wheel and more like an hour glass with inlaid gold added for weight. The ref. 5550P encapsulates the brand's total efforts in Silinvar research to date and has three areas of the movement done in Silinvar. Now, get ready to remember some vocabulary.The three areas of the watch done in Silinvar are the GryomaxSi balance wheel, the Pulsomax escapement (two parts which includes the escapement wheel and anchor in Silinvar), and the Spiromax balance spring. Patek Philippe first began using silicon parts a few year

Omega 2251.50
Hello,I have become quite interested in purchasing a Seamaster 2251.50 however am having a hard time trying to source a store that actualy has any in stock. I have attached some photos of the watch as if your anything like me serial numbers are of no real help.It is such an understated watch but very beautiful in my eyes. A perfect watch. With the American excnahge rate so strong it seemed to be a logical time to pruse a purcahse.Any advice would be appreciated.

Better sidekick to the No Date Sub
TRF'ers...in your opinion, disregarding what else may be in the collection, what's a better piece to pair with the No Date Sub (114060):-Explorer 1 (updated 214270 with lumed numerals and longer hands)-GMTC II LNWould the Explorer be too similar in that it is another no date/time only, black dial Rolex with the Mercedes hands, with 'similar' brushed oyster bracelet? Or would it pair nicely in with its smooth bezel, different hour markers on the dial (with the Arabic numerals) and generally wears differently than a sub?Would the GMTC be too similar as it is another black dial Rolex that has a rotating bezel, similar hour markers on the dial, and wears somewhat similar to the sub? Or would it pair nicely as it has the date/cyclops, bezel (while rotating) like the sub) is different, polished center links, and added GMT complication?Looking for opinions and would love to hear from owners who own both of the different pairings. Thanks in advance.
