Description
A mechanical watch movement is a city in miniature, hundreds of parts working in agreed silence. The 2813 caliber is one of the most widely used automatic movements in the world, and this specimen is built to the standard specification: three hands, a date wheel, and 21,600 beats per hour.
Watchmakers and repair shops stock the 2813 for a simple reason: it is the workhorse of the trade. When a customer brings in a watch that runs on the DG2813 platform, this movement drops in with the same dimensions and stem height, turning a repair into a routine job rather than a hunt for parts.
It winds automatically with the motion of the wrist, holds its reserve through the night, and the date changes cleanly around midnight. The white date wheel with standard numerals keeps the dial legible, and the finishing is consistent with the caliber that has powered a generation of affordable mechanical watches.
For the home builder, the 2813 is the classic first movement: forgiving to handle, widely documented, and compatible with a large range of cases, dials and hands. A pair of tweezers, a screwdriver, and an afternoon are enough to see one running on the bench.
A small machine that keeps its own time.

Frequently Asked Questions
Q: Which watches does this movement fit?
A: It fits watches built on the DG2813 platform with standard stem height and dimensions, the most common budget automatic layout.
Q: What is the beat rate?
A: 21,600 beats per hour, the standard frequency for this caliber, visible in the smooth sweep of the second hand.
Q: Does it include the date function?
A: Yes, the movement includes a date wheel that advances automatically around midnight.
Q: Is it self-winding?
A: Yes, the rotor winds the mainspring with wrist motion, and the movement also accepts manual winding.
Q: What does the set include?
A: The movement itself, ready to install in a compatible case with the dial and hands.
Q: Is this movement new?
A: Yes, it is a brand new unit, not a refurbished or pulled movement.
Q: Can it be serviced with standard tools?
A: Yes, it follows the standard 2813 service layout, which is well documented and familiar to watchmakers.
Q: Is the date wheel white or black?
A: This unit ships with a white date wheel with standard numerals, which suits most dials and keeps the window legible.
Q: Can I set the date independently?
A: Yes, the crown position for date setting works as standard, letting you advance the date wheel without moving the hands through the midnight window.
Q: Why do watchmakers prefer the 2813 for repairs?
A: Because it is the most common budget automatic caliber, parts are plentiful, service documentation is extensive, and the drop-in fit means a repair does not become a custom job.
Q: Does the movement include a second hand?
A: Yes, the three-hand layout includes a sweeping center second hand, which runs at the 21,600 bph beat rate and is the visual signature of this caliber.
Q: How long is the power reserve?
A: The mainspring holds enough reserve to keep the movement running through the night after a day of wear, which is the standard expectation for this caliber.
Q: What stem height does this movement use?
A: It matches the standard DG2813 stem height, which is why it drops into cases built for the 2813 platform without modification.
