I have one of the 15 Sea Anglers from the series that was out earlier this year. I believe Berg sold some on eBay. Does this watch have a mineral or sapphire crystal?  Cheers, gigfy |

Try the water drop test. If the water forms drops you probably have a sapphire. If it spreads its probably mineral. I say probably because I've done this and sometimes received curious results. |

the sapphire crystals on the early Sea Anglers ( orangia,black,silver surfer,lume dials) were a $60. option during pre-order ...so if it was not ordered with that option it would be a mineral hand6.gif ...the one you have was the last batch made and I was unaware of the option being offered but Berg would know if any were made with saph crystals to order... watch2.gif |

It sort of formed a bulge. I then went to one of my officemates, grabbed his wrist and did the same on his Swatch quartzie and the water actually spread and imediately and rapidly flowed to the bezel edges. Man!!! This is good stuff, Markhand6.gif Will this drop test work with single malt???? |

I say probably because I've done this and sometimes received curious results. I tried this trick and it worked every times...On real sapphire crystal, the drop form a clean bubble. If it spray, even not much, it's not sapphire. Offcourse: Depose a little water drop...Mineral will spray the drop in different shape: Not as much as a hard plexi but still... This got to do with the very high density of sapphire crystal who's like the natural corodum(sapphire, ruby): 9 on Moh's hardness scale. Diamond is 10. So the water don't find micro-cracks to spray itself in. Offcourse, the sapphire surface have to be polished clean like it's on a watch crystal: Don't try this on a slightly cracked natural corodum stone.... I've been reading a topic about reparing lightly scratched sapphire glass yourself: Use Diamond past (2.5 microns) and rub the scratched surface with a little piece of ragg for 2-3 minuts. Clean it up and if the trace disappeared, finish with a 0.5 micron D.past by doing the same thing. Protect your bezel during operation! ;) The guy fixed his Pam like that: Instead of buying a new VERY expensive crystal... It make sens to me: The diamond-past is apparently a compound with microscopic diamond powder. As the diamond is harder than the sapphire, it polish it and erase the tiny scars who was made accidently by "banging a door frame". Hard steel: Specialy when it's sharp can dig it's way into sapphire as you may know... |

Great tip Mark...another that an old watchmaker showed me years ago when I collected vintage is if you hold the watch against your cheek and it feels cold it was a glass crystal, if it was warm it was plastic |

Supposely because the high density does that the material don't absorb heat easyly. Still, a mineral glass feels cold...Mineral glass is just usual glass who's hardened so it's not as hard as sapphire glass but it feels cold. The drop of water will spray on mineral glass: Not on the sapphire. |

so did someone confirm whether the latest 09 Sea Angler had Saphire cyrstals? |

Brice...if you are talking about the October-November 2009 vintage Sea Anglers (the ones just available a few ago), they have the Hardlex mineral crystal installed. I happened to ask Martin this very question when I picked mine up a few weeks ago. |

I say probably because I've done this and sometimes received curious results. What a great trick! Just went to do the test in the office with the Hami Monte-Carlo I am wearing, and the drop stayed put (even though it is a domed crystal). Tried with a Marina Militare I have in the drawer waiting its turn to go home (:D), and it spread instantly! On another note, anyone seeing a WIS doing this test will be more convinced that we lost more than one screw... Last edited on Fri Dec 11th, 2009 02:15 pm by ral |
