This model comes in excellent condition. The strong and thick stainless steel case gives it a very nice presence, while the original and rare Gay Frères steel bracelet brings the real toolwatch feel. The particularity of this watch is its unseen numeral dial. In perfect condition, this type of dial and fonts has appeared on some rare time-only caliber 83 pieces, but almost never on an Ingenieur. It is actually the only known example to have ever surfaced on the market.
