Great looking Heuer Monaco that has undergone some aesthetic and conscientious restoration to lume by well known Heuer expert. Excellent condition and recently serviced (2015) which included replacement of seal, pushers and crystal (all original parts) with full movement stripdown, lube and re-assemble. No (zero) seal leak/melt to dial. Unpolished case, original crown and pushers, hands and dial. Looks great on wrist but far too large for me! Works flawlessly and maintains excellent time. A great classic. Will trade for Universal Geneve Tri-Compax or aero compax with cash depending on model. Oversize preferred. Value according to Vintage Heuer Price Guide website: http://www.heuerpriceguide.com/#/monaco/4561058325 good/excellent
