What Does 'AS' Mean on a Vintage Watch Movement?
If you have ever looked inside a vintage watch - or seen a description mentioning the movement - you may have come across the letters AS, often followed by a number, such as AS 1700 or AS 1950. It is one of the most commonly seen markings on vintage movements, and it puzzles many owners. The answer is genuinely interesting, and it tells you something real about the watch. Here is everything you need to know.
What Does AS Mean?
On a vintage watch movement, the letters AS stand for A. Schild - one of the largest and most important movement makers in the history of Swiss watchmaking. So when you see AS on a movement, it means the movement was made by A. Schild, and any number that follows, such as AS 1700, is the calibre number identifying that particular movement.
Crucially, A. Schild was not a watch brand in its own right - it was a specialist movement maker, an ébauche maker, supplying movements to a huge range of watch brands who would then fit them into their own watches, as we explain in our complete guide to vintage watch movement makers. This is why you may find an AS movement inside a watch carrying a quite different name on the dial - the brand made the watch, but A. Schild made the movement at its heart.
Who Was A. Schild?
A. Schild was one of the great specialist movement manufacturers of the Swiss watch industry. Rather than making complete watches under its own name, the firm specialised in producing movements - in very large numbers, and to a genuine standard of quality - which it supplied to countless watch brands.
A. Schild became one of the most prolific and important ébauche makers of all, and its movements found their way into an enormous number of vintage watches across a huge variety of brands. This is precisely why an AS movement is one of the most commonly encountered of all vintage calibres - the firm supplied so many movements, to so many brands, over so many years, that they turn up inside vintage watches of all kinds. For the vintage enthusiast, A. Schild is one of the first movement-maker names to become familiar.
Are AS Movements Any Good?
This is the key question for many owners, and the answer is reassuring. AS movements have a genuinely good reputation. They are well regarded as reliable, well-made, dependable workhorse movements - the kind that keep running faithfully, decade after decade, and that a watchmaker can readily service.
Because A. Schild made movements in such numbers, and across a range of grades, AS calibres powered everything from modest everyday watches to more elevated pieces. But the common thread is genuine quality and reliability. An AS movement is nothing to be disappointed by - quite the opposite. It is a sound, dependable, serviceable movement with a proven track record, and finding one inside a vintage watch is a mark of honest, quality engineering. The fact that so many are still running beautifully today is testament to how well made they were.
Why the Movement Name Differs From the Dial
For anyone new to vintage watches, it can be puzzling to find one name on the dial and another, such as AS, on the movement. But as we explore in our guide to vintage watch movement makers, this was completely normal and entirely legitimate. A great many watch brands did not make their own movements, but bought them in from specialist ébauche makers like A. Schild, then finished and fitted them under their own name.
So a vintage watch with an AS movement is exactly as it should be - a genuine watch from its brand, powered by a quality bought-in movement from one of the great specialist makers. Far from being a concern, it is simply how a large part of the industry worked, and the AS movement inside is part of the watch's genuine character and history.
How to Spot an AS Movement
If you are curious whether your vintage watch has an A. Schild movement, the marking is found on the movement itself, inside the caseback - not on the dial. On the movement, you may see the letters AS, or the A. Schild name or maker's mark, together with a calibre number such as AS 1700, 1701, 1950, and so on. These markings identify both the maker and the specific calibre.
