A.Lange Catalogue and Price List
PUBLICATIONS - A.Lange & SJust received the 2009 Catalogue: State of the Art Tradition to go with my 2008 version. I'm still sticking to the Lange 1 series and was hoping to possibly see an added leaflet of the 2010 Basel Release (Lange 1 Day-matic) . I'll just have to wait for the Watch magazine publications for more details on this upcoming model to the legendary line. I know that GO adds newer release models to a smaller flyer/booklet if they can't fit it into their standing catalogue. Nothing on the Day-matic in this catalgogue though, it's all about the 31-day and the ZEITWERK technical/horology!

Breitling Callistino Crown - not sure if faulty
I have a pre-owned Callistino. The crown seemed to be screwed down when I got it. It was tight and did not turn. The clocks went back last week (end of British summertime) so I had to adjust the watch. The instructions say to "pull the crown out to position 3 and adjust the hour and minute". Then it says return the crown to position 1. Since the time adjustment has been carried out the crown won't return to a screwed tight position and rotates freely. I'm a bit concerned about the water resistance on account of this. Any advice please.

Was hoping to get some feedback from those who are more knowledgable than me about the authenticity of this watch.It's a vintage 1970s sea master calibre 1020 just like the one in this videohttps://m.youtube/watch?v=W7Rby0j6RQ0I'm particularly dubious of the hippocampus as it seems to be a rather low res stampingAppreciate any feedback, thanks

Thread: I tried on the Blue Ti PO three hander today...
It was the first one ever that the Omega boutique in Crown Casino have got in. it was the one with the Ti bracelet.some observations:1. size perception - this watch looks bigger than the 45.5mm in black ceramic, must be due to the black/dark grey, makes it look visually smaller. but both look much better than the 42mm versions - they look and wear really small compared to the 2500 42's2. thickness - quite thick, but not massively so. i expect the Chrono to be much thicker, which could be an issue for me potentially. i feel the thickness of this three-hander is about as thick as most people would want/accept as a balance on the wrist3. the watch is incredibly light. i was surprised just how light it is. it's so light that some might think its too light, almost toy-like.. but on the other hand its a key unique feature for those that like larger watches but not the added weight as its non-Ti 45.5mm siblings are quite hefty4. the Titanium colour - is superb, as reported looks just like sta
