A Watch Is Not Told. It Is Worn. It Is Built.
There is a reason the 2813 remains the most serviced automatic caliber in the watchmaker's drawer: it does the one thing a mechanical movement must do, which is run, and it does it at a price that keeps the craft accessible. This DG2813 automatic movement beats at 21,600 vibrations per hour, sweeping the seconds hand with the smooth glide that quartz cannot imitate. For repairers, modders, and first-time builders, it is the caliber that turns a parts tray into a working watch.
The 21,600 bph beat rate is the heart of its character. Higher than the slow-beat movements of the past, lower than the race-derived calibers of the present, it sits in the sweet spot of reliability and tradition: a rhythm you can feel through the case, a reserve of mechanical energy that winds itself as you wear it. The automatic rotor tops up the mainspring with every turn of the wrist, and manual winding is available for when the watch has sat overnight on the bench.
Standard specification matters when you are building or repairing. The DG2813 uses the familiar three-hand layout with a date window at three o'clock, dimensions and stem positions that drop into the cases and dials made for the 2813 family, and parts sourcing that is straightforward for any workshop. Whether you are reviving a family watch, completing a mod build, or teaching yourself the discipline of the escapement, this movement gives you a clean, honest foundation to work from.
Quartz tells time. This keeps a craft alive.

Application Scenarios
The Caliber 2813 serves the three communities that keep mechanical watches alive. Repair workshops fit it when an original movement is beyond economic repair, returning heirloom watches to service with dependable running gear. Modders use it as the engine for custom builds: skeleton dials, custom rotors, and aftermarket cases all accept the standard 2813 layout. Students of watchmaking use it to learn the trade, because every component is available, serviceable, and forgiving of the beginner's mistakes. For anyone who buys watch parts in volume, the consistent specification and batch performance make it the reliable workhorse of the parts tray.
Frequently Asked Questions
Q: Is this movement suitable for a beginner watch builder?
A: Yes. The DG2813 is one of the most documented calibers in watchmaking, with standard dimensions, widely available parts, and forgiving assembly tolerances. It is the classic first movement.
Q: Does it hack (stop the seconds hand when setting)?
A: This 2813 specification does not include a hacking function. The seconds hand continues running while the time is set, which is standard for this caliber family.
Q: How long is the power reserve?
A: Approximately 40 hours on a full wind, enough to survive a night on the nightstand and most of a weekend off the wrist.
Q: Will it fit my existing 2813 watch case?
A: The DG2813 follows the standard 2813 dimensions and stem position, so it drops into cases, dials, and hands made for the 2813 family.
Q: Can I wind it manually?
A: Yes. It winds automatically through the rotor during wear, and the crown also supports manual winding when the watch has been sitting.
Q: Does the movement come with hands and a crown?
A: No. The movement ships alone; hands, dial, crown, and case are sourced separately to match your build, which is standard practice for watch parts.
Q: Is the movement new or refurbished?
A: The calibers are new, standard-specification movements. They are not refurbished, and each one is inspected before dispatch.
