The Omega Speedmaster is widely considered one of Omega's most recognised and historically significant timepieces, having been involved in all six lunar missions, and giving Omega a heritage to be proud of. Adding further interest and detail to this already well established design, Omega have now added a photo-realistic moonphase onto the dial. This 44.25 mm model features a black gloss sun-brushed dial, with rhodium-plated indexes and hands. At 6 o'clock is the accurate Moonphase indication, which features a metallic crystal disc specially crafted to clearly show a high resolution image of the moon.

Furthermore, this timepiece as part of Omega's 'Master Chronometer' family of watches, meaning it has passed rigorous testing by METAS (The Swiss Federal Institute of Metrology) and powering the timepiece is the well regarded OMEGA Co-Axial Master Chronometer 9904 movement. Featuring a stainless steel case and link bracelet, with two sub dials, chronograph function and see through case back.

Supplied in Mint condition, this watch is a complete set with all original inner and outer presentation boxes, with instruction manual, warranty, pictogram and master chronometer card. This watch is protected under Omega warranty until 2022.

Dear Dee, Please accept my apologies for having taken so long to acknowledge receipt of the Rolex GMT that I found on line and then spoke to you on the telephone from the Isle of Man before purchasing. I received it on Tuesday of last week. Although thrilled I was nervous having spent rather a large amount of money using only pictures and verbal assurance. I waited until the evening when all was done and calm to open the parcel. I was thrilled with what I saw. The watch was running and the time was correct so I inspected it, placed it on my wrist and read through the enclosed paperwork. It was like welcoming an old friend back into the fold. I have worn it every day since receipt and smile every time I check the time or use the bezel. I am so very glad that ‘Island Fever’ got the better of me but more importantly know that I can trust your site and especially your word and guidance. Thank you. I have one or two other watches including a Tudor Pelagos Blue Titanium and had seen some very favourable reviews of the Tudor GMT that had tempted me but I am so very glad that I stuck with what I wanted. When I had my GMT 20+ years ago it was a big watch. It’s a slim-line tonic by todays watches and relatively light. Most importantly to me it is a joy. Very many thanks, Dee and I shall make a point to drop in if/when I get my act together and visit my friend in Chiswick. In the meantime I have to resist your site and continue to enjoy what I have – which is very easy. Very Best Regards, Ian
