Maurice Lacroix Masterpiece Regulateur Roue Carree Watch
I am talking about this watch because people are going to notice it and wonder, "what is going on here?" Well nothing really fancy to be honest, aside from some engineering gear fun. While the concept of a clover and square shaped gear might be odd, it works. You can see in the video exactly how if you aren't too mechanically minded. Maurice Lacroix talks about the watch as though they just invented a time machine - but luxury brands are all about hyperbole, so I can forgive them (to an extent). Ahem, have a listen: "Maurice Lacroix has chosen its flagship Masterpiece line to open a new dimension in watchmaking" (I giggle and snicker). "This is a response to the brand's ambition to take design and the mastery of watchmaking even further." WowOK Maurice Lacroix all this for a few gears? I mean the watch is neat looking, but it doesn't really offer a dynamic change to the game.Movement is a Maurice Lacroix made ML 153 manually wound movement which is in-house made. It has 48 hours of pow

Specifications and characteristics of Jaeger LeCoultre's OTHER DivingWatch
It is important, as also the Polaris, MLC was not really much to offer real divers in the 1960s and 1970s. Their captain long was there, but let's be honest, that is not a true diving watch. Deep Sea master course, however, is supposed to certainly be worn under the water. It has a compressor case, a refracting telescope of rotation internal and smooth operation JLC movement with date window.

Birth year watch - 1971
So, I'm about to give up my search for the blue dial Hamilton PanEurop, what are other recommendations for watches produced in 1971?

Would you sell.....
More of a fun thread.Would you sell a single sealed 5131G bought at retail price in this market?...seems like prices have hit the ceiling, I can't see them going much higher....and if a P launches would that hurt grey market value of this (~$140-150)

Crown guard help ...
Question related to service...After several years of heavy use, my old man is giving me his Panerai 299. While generally in good shape, the crown guard is pretty loose and jiggles around. Certainly not useful any more in preventing ingress of water. Is there a way to tighten it myself using inexpensive tools I can buy online, or would you recommend bringing it in to an AD for service/sending it to Panerai. All else being equal or nearly equal, I'd prefer the lowest-cost option. Thanks!
