Mark has a core of very satisfied customers - as demonstrated by his eBay feedback.
He also has some extremely unhappy customers. Most of that unhappiness is centred around the authenticity (or otherwise) of the papers that often accompany the watches he sells.
When a few folk raised their concerns on this forum about Mark's practices a few months back - levelling some fairly serious allegations towards him - Mark chose not to respond. You may like to search "Mark Lerman" on VRF, read the discussions from a few months back and make your own judgement.
IMPORTANT: I've had no personal dealings with Mark so am simply bringing your attention to the discussion from a few months back.
I don't know about the printing on that dial. I'm far from the authority..you're much better off listening to the other guys, but the printing seems way wrong. Check out the dial archive. Also, I'm curious if other forum members have seen the uneven 5513 on the caseback before, where the 13 is stamped higher than the 55. Is this common? I've never seen that before either.
That and the paper thing...I dunno. These watches aren't that hard to find.
Around these parts he is more of a black sheep. I have never seen him post a watch for sale on these or other forums (only on ebay) and his reputation is questionable because of the alleged fake papers he seems to provide with EVERY watch he sells. My only concern is that he seems to be the only seller in the world that is able to provide complete or partial set watches with stamped/punched papers with the vast majority of watches he sells.
In reality, the rarity of finding a 45 year old watch that still has its accompanying paperwork is probably under 5%. I know people who bought watches in the 2000's that have misplaced their boxes and papers so, its unlikely that all of his full sets are genuine.
Much thanks goes to those members of this forum who were smart enough and brave enough to out him and his practices a while ago and protect the real collectors from being taken.
I wouldn't pay the typical premium associated with vintage box/papers from him. His watches, for the most part, are fine, and are what they are, some pretty nice. Read the description + pretty good pics and bid accordingly, but for heavens sake don't pay a premium for any papers that come with his watches.
i have had a few emails with this guy and also won an auction about a year or two ago - after i won the auction i sant a pic of the dial to one of our good buddies on here and i was told the dial was touched up first generation and he also referred me to doubleredseadweller.com which has a lot of great facts - when i called Mark on the dial issues he said thanks for telling me and let me off the hook for payment. after that the watch was re-listed for sale and sold to another buyer and if you notice all the buyer feedback is private - i suppose he doesnt want ebayers contacting eachother about his dealings if you catch my drift
some of the watches he sells look very nice and i am no expert on dials or cases but after that one experience and from what i have read i would be careful when buying unless your fingers have no control like when you get drunk dialing fingers and call some girl you know you should be staying away from lol
