I'm planning on buying a Seiko Sarb033 from amazon. But the product description says "Silver Toned" in color. I'm not sure what does that mean. I like the usual stainless steel color of the watches but what's silver toned? Is it the yellowish color tone on the watch. Isn't the part or the model number of a watch unique to its color, design etc. Can there be 2 watches with same model number one with usual polished stainless steel color and one with "silver toned" stainless steel? I'm thoroughly confused.
