This is the discontinued 36mm model ref 754.7551.43.61.LS.
Stainless steel with RG coin edge bezel. Domed acrylic crystal. ETA 2824-2 automatic.
Watch is in excellent condition and keeping accurate time. I purchased it used and recently had the movement overhauled (cost $352.00 AUD) including a new winding pinion. Receipt can be provided. I also replaced the original strap with a nice quality Hirsch Duke (medium length) of similar appearance. The strap is very lightly used and the original buckle is attached.
The RRP on this watch when available was around $1,100.00 USD. My price is $630.00 USD. Watch only, shipping extra at cost to your location.
