Omega 3882.31.37. Asking $4000 USD shipped from Calgary, Canada by ParcelPro. Selling this one as I do not wear it, and it should be on a wrist somewhere...... The good: Calibre: Omega 3612, Self-winding chronograph movement with column wheelmechanism and Co-Axial escapement for greater precision, stability, and durability of the movement. Free sprung balance, with date, hour-, minute- and continuous small seconds-hands, central chronograph hand. Tachymeter and Pulsometer scale for those gone frantic by the "new" Basel offering from Omega. Column wheel split-seconds mechanism. 52 hours power reserve. All working as it should. 44.25 mm stainless steel speedmaster case with 21 mm lug width. I have some 21mm end links if you want them. 100m WR, sapphire crystal front and back. The bad(so priced accordingly): no box and papers. There is a case ding that I have photographed next to the 77 on the tachymeter scale. Aftermarket leather rally-style strap. IF you want a safe queen or a full set please move along and have a nice day. Please look at the pictures, if you wish more information or different pictures please let me know:
