I think it is unclear whether you already own the watch or considering buying it, or just the bracelet. Some of the comments are meant to advise you on the watch itself- if you already own it and know its a redial, not to worry- it is an attractive watch and you should wear and enjoy it! Have you opened it and checked the inside of caseback for reference, and the serial number on movement and movement caliber number- those things help further assess the watch itself- if that would be helpful to you. I believe the 2852 was introduced in 1956 rather than 1954.
Keep in mind there are issues that may be important to a collector, but not so much to a non-collector such as whether the dial is refinished. You can show this watch to 100 people and probably 0-1 will be able to tell the difference. The 0-1 folks are likely on OF!

These Constellations from the 50's were generally sold on a leather strap, but buyers could order a bracelet if they wished at point of sale. Here is Desmonds guide to bracelets:
