Product description

BN2031-85E (display model)

For the 30th anniversary of Promaster, Citizen developed seven new ISO 6425 certified diving watches. They feature a new look with proven functions. The Aqualand BN2031-85E has a depth gauge, power reserve indicator, max. dive depth memory, shock detection function, battery discharge indicator, and decompression alarm. The power reserve of the Eco-Drive movement is 330 days. A crystal glass crowns the matte silver stainless steel case, and the bezel is unidirectional with a minute scale and luminous marker. It has a black stainless steel bracelet with a safety folding clasp, luminescent hands and indices that are visible on the black dial. A date display is at the 3 o'clock position.

This watch is an exhibition piece that was displayed in our store and has minimal signs of wear. It is unworn, in its original packaging, and comes with all papers. A great offer for people who will use the watch and know that every watch will be in this condition after a few days of wear.

The two purchased 90s Swatch are in absolutely mint condition, with original protective film on the watch glass and an equally "untouched" original box.

I was looking for a replacement Swatch strap that was impossible to find in the UK, so ended up on Watch Papst due to lack of options. To my surprise it took only 5 days to arrive from Germany so wouldn't hesitate next time! Part was as described and packed well.

Delivery was made as quickly as possible after receipt of the advance payment.
I was especially pleased that the watch was from Citizen It was not delivered in the usual black box, but with the yellow diving cylinder.
I can watch Papst, who watches from Citizen, Union Glashütte, Mido, Swatch or Tissot I highly recommend his professional work and great service.

Everything was perfect - the watch arrived with a new battery and the correct time set, even though it's a relic from 1996.

A huge selection of watch straps, even for older models that are no longer in production. This allows me to continue wearing the watch. With a new strap, it's like new again.

Excellent experience; I was looking for a watch that was no longer available in stores until I found it while searching online. Swatch Papst I stumbled upon it and found the watch I was looking for – simply great, highly recommended!
Thank you for the fast delivery.

Fast shipping of my desired watch. I particularly appreciated the discreet packaging, which didn't reveal what was inside.
