Bad/Bogus Pulsar glass: Pictures and tests

Post03 Jul 2007, 16:53

[THREAD LOCKED FOR SANITY and so we can move on. Start new thread]
With much regret(and after discussing it with people I consider highly reputible) I have to bring this development to light. A large number of NOS Pulsar glass recently entered the market. Thru a fortuitous glass exchange, I have come to the strongly held opinion that they are IMITATIONS WITH PAINTED ON LOGOS THAT WILL COME OFF WITHOUT A TRACE!! The glass "blank" seems legitimate(tested with MOHs hardness tester against known original glass), but the logos CANNOT withstand the common method of heating the entire watch(sans module of course) to 350 f. to loosen the epoxy. These logos can also be scrubbed off with a common plastic kitchen scrubber and water, leaving NOT A TRACE of their previous existance on the glass, unlike the originals which leave a logo shapped "haze" on the glass which requires a good amount of polishing to eradicate. The logo on a real Pulsar screen can withstand a great amount of abrasion, wearing off in small amounts at the corners of the logos and able to be scratched in a thin line across the logo, without any of the adjacent logo "flaking" off.....behaving much like porcaline.

The good news: the bogus screens were printed in a slightly different font, and in conjunction with a few other collectors we will be posting hi-resolution pictures of the real deal and the imitations, for comparision, over the next few days.

The bogus screens are also printed in a slightly "off" colorization, especially the gold logo version, which has a slightly mustard color, and a flat finish unlike the originals which had a slight gloss or "satin" to their finish.

I hate being the one to bring this out, but I would have hated being the one NOT to bring this out. I have personally lost a substantial amount on this "deal", and will only be able to sell this glass as legitimate P2 glass, after scrubbing the bogus logos off. To "return" the glass to the seller would only perpetuate the damage I'm afraid.

Test with non-acetone nailpolish remover on a facial tissue.
After 25 stokes across you have this with the bogus crystals.

Genuine Pulsar glass after same test. No change IMO.

Real - note nice puffed glass appearance of letters, this gives the letters a raised profile, as opposed to the fakes which use a wider, but flatter line to give almost the same impression to the naked eye,

Fake.
Much flatter in height/profile. Made of small crystals or flakes. Much flatter lines to the characters.

The faker after twenty five passed of my fingernail across the logo...I'd give it another 25 and it would be gone completely.

Further looks at how the other Pulsar related companies were using same process.
