The Zenith Diver Ref. A3637 is a rare diving watch from the 1960s with an eye-catching design.

The nickname "Big Sea Blue" is pretty obvious: a large 43mm case combined with striking blue colors

. The dial is absolutely clean and free of scratches. The large hour markers have original tritium lume with an orange border. The hand set features a big orange minute hand, a paddle seconds hand and an orange hour hand. The date window is between 4 and 5 o'clock.

The blue bakelite bezel shows orange minute markings along with numbers and a yellow triangle at 12 o'clock. The bezel can be turned in both directions and it is preserved in excellent condition. The stainless steel case has hardly any signs of wear. The case back is screwed and shows the large zenith NATO star in the middle.

The heart of this vintage watch is the Zenith automatic caliber 2552PC, which is keeping very good time to this day.

This Zenith A3637 is a rare vintage beauty and an ideal summer watch with a flashy design and reliable mechanics.
