The Armand Nicolet AN2846-9 is essentially an ETA 2846 with a custom Armand Nicolet branded rotor.

ETA 2846 Base

The Armand Nicolet AN2846-9 is essentially an ETA 2846 with a custom Armand Nicolet branded rotor – hence the 2846 in the caliber number.The base 2846 movements typically have 17 or 21 jewels, the AN has 23.

Although marketing material makes it sound like this movement is proprietary to Armand Nicolet, they left the ETA logo and 2846 caliber number etched into the plate below the balance wheel.

The ETA 2846 was discontinued circa 2006. It’s likely that AN came across new old stock movements and customized and regulated them in-house. AN’s 2015 catalog mentions some of their other calibers being sourced NOS and refinished in-house. For example, they acquired a caliber UT 600 that was originally produced in 1957, and after modifying and refinishing it, the movement became caliber AN0711A.

Bonjour à tous les passionnés d’horlogerie, Je suis l’heureux possesseur d’une Montre Armand Nicolet J09 Black Rally Leather strap automatique 39mm 1ère génération. Ma montre est équipée de ce Calibre AN 2846 sur base ETA (doté de finissions exemplaires, voir photos). Pour le reste, c’est du bon ETA, précision de +/- 5 sec /jour et une réserve de marche confortable. Montre sport mais chic qui s’adapte à toutes les situations, verre saphir réellement inrayable: je suis horloger réparateur et je fait de la micro-mécanique en la gardant au poignet. Je n’ai jamais eu le moindre problème avec, même lorsque je… Read more »

Most acurate watch I had – even better than my Ball Chronometer which is spot on – has been the Armand Nicolet M02, with a top grade Eta movement rebuilt, signed and timed by them. Just sent it to them for a service as don’t trust anyone else to regulate it as well, despite the fact ‘anyone’ can service an Eta movement.
