I was looking at Russia 2 All and saw they were having a special on the red square with repolished cases. So I have a couple of questions. What exactly is repolished? And it is a gold case with either a black or white dial. so black or white?

It simply means they buffed or polished the case to remove the light tarnish supposedly acquired in shipping. The black dial is the one to have. Very handsome. I'd get a polish cloth or jeweler's cloth though to keep the tarnish from coming back. Watch Prince has them.

Hmmmm! http://www.corrosion-doctors.org/MatSelect/corrgold.htm#Tarnishing Gold Corrosion Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Gold tarnish is very thin and shows up as a darkening of reflecting surfaces. Compare the thermodynamic or chemical energy of metalsGold is among the most electrically conductive of all metals. Since electricity is basically the flow of charged particles in a current, metals that are conductive allow this current to flow unimpeded. Gold is able to convey even a tiny electrical current in temperatures varying from -55° to +200° centigrade. A modern and comprehensive document on the subject is the second edition of the classic CORROSION BASICS textbook. "Purple plague" is a brittle gold aluminum compound formed when bonding gold to aluminum. The growth of such a compound can cause failure in microelectronic interconnection bonds.Gold reference)
The tarnish films formed are generally harmless although unsightly and may lead to a black smudging of the skin. Such films can be easily polished off by a jeweler to restore the bright gold color.

It's a great watch. The above description of repolishing is accurate. I haven't seen the special offer but can't imagine there would be much downside.

Seems to be two diametrically opposing statements here... "Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. 1) Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. 2) Gold tarnish is very thin and shows up as a darkening of reflecting surfaces." Well, excuuuuse me, BUT...if gold will not rust or tarnish, then how can one say that gold tarnish is very thin....yadda, yadda, yadda? HA!

If it is 9 kt. (used in Europe) or so, the impurities could cause the plating to tarnish. Pure gold won't tarnish. Yes, the first article contradicts itself. :) Alloys To keep costs down and make Gold harder, goldworkers often alloy it with other metals, usually Copper or Silver. Mixing Gold with these other metals changes its color. The following are the major types of Gold Alloys: Blue Gold: Gold with Iron Green Gold: Gold mixed with a higher Silver content than Copper Pink Gold (or Rose Gold): 50% Gold, 45% Copper and 5% Silver White Gold: Gold with Nickel, Zinc, Copper, Tin and Manganese-Nickel is only used in White Gold because it bleaches Gold Yellow Gold: 50% Gold, 25% Silver and 25% Copper Measuring Gold Jewelers indicate the amount of gold in an alloy by the Karat system. 24kt.: 100% Gold-very soft 18kt.: 75% Gold-will not tarnish; softer than 14kt., but with a deeper color 14kt.: 58.33% Gold-will not tarnish 12kt.: 50% Gold 10kt.: 41.6% Gold less than 10kt. cannot be called Gold in the US or 9kt. in the UK. Gold Tarnishing To avoid tarnishing Gold, you should be aware of metallic abrasion caused by cosmetics or clothing, wet conditions that can corrode the metals used in Gold alloys, perspiration, and the chemicals in swimming pools. Higher karat Gold Jewelry will be more resistant to tarnishing.
