1999 Omega (Swiss) Speedmaster Ref. 3510.50.00 Automatic Chronograph – Cal. 3220


Out of stock

From 1999, an Omega Ref. 3510.50.00 Speedmaster automatic chronograph watch in excellent condition. This all original automatic chronograph (a.k.a. ‘reduced’) timepiece has been professionally serviced by Localtime.

A truly classic watch (and in my humble opinion one of the best-value-for-money watch models in the market) that really needs no introduction. I have changed the crown with an original one from Omega (photo attached), as the crown that it had on, was wrong for this model. I have made many photos of the watch, including a few fun closeup snapshots I took for fun, to show the details! This classic timepiece is in excellent condition throughout and is wearing one of my own deployment gator-grain leather straps in black, with white stitching, that compliments the watch very well..

As with all the watches that are handled by Localtime, the listed price includes a written 6-month written warranty from the date of purchase. Feel free to contact me for whatever questions you might have.

Extra: Try my Localtime premium calf leather straps with deployante buckleWe all fear the time when the time comes to change the strap on one of our nice watches and the local AD will quote us something in the region of $200 plus. Now there are nice alternatives. These straps are not expensive and the quality is great, so I’d call them a decent value for your money. I have found them to be very comfortable and a great match especially for dress watches and chronographs that will combine well with this style of straps. They come in 3 sizes (18-20-22mm), and 7 choices of texture, leather colour and stitch colour. Their length is approximately 75/125mm except the smooth leather ones which are 75/115mm. They have two keepers, one of them is fixed and the other one is floating, for a better fit and comfort. A good quality pair of spring bars is included with each strap. You can see them in the last photo here and/or purchase them separately under eBay item 132928544124. Feel free to contact me for whatever questions you might have.

Important Note: Sometimes I am asked what I exactly mean with ‘professionally inspected by Localtime’. Here is my theory on vintage watches: as a purveyor of vintage watches, my effort is to always do only what is needed to the watch. I do not buy ‘junk’ watches to resell. I am choosy with my purchases and always sell watches that are, to my knowledge, authentic and in good condition. I first inspect the watch, both visually (cosmetically) and then mechanically. If I judge that the watch is not yet in need of a full service then I do not put the watch through a service which, by the way, entails a lot of risks too. Instead, I give it what I call my ‘Spa’ treatment which will include a cleaning, changing of gaskets, oiling, lubricating and mechanical testing. If the plexi is heavily scratched or discoloured and it can not be cleaned, I change it. If the crown is wrong or worn, I also change it. Now, if the watch is in need of a full service, then my ‘professionally inspected’ description becomes ‘professionally serviced’. In both cases, I include a written warrantee with my buy it now price and I always describe what I have changed, if anything, on the watch.

Important Note On Straps/Bracelets:The straps I use on my watches [leather, canvas, suede, rubber] are always brand new, unless otherwise mentioned and, in most cases, I also sell them separately in my store, in different colours and sizes. In the case of metal bracelets, if the watch is NOS, the bracelet is also unused. If the watch is pre-owned with its original bracelet, then the bracelet is also pre-owned, unless otherwise mentioned. Either way, if in doubt, please ask.
