Sellita Caliber SW260-1

The Sellita caliber SW260-1 is a Swiss made automatic movement 31 jewels and a frequency of 28,800vph.

The notable feature of this movement is the small seconds subdial at 6:00. This is typically found on manual-wind movements such as vintage pocket watches, so it’s nice to see the option available on an auto.

SW260-1 VS SW261-1:

There is a very similar Sellita caliber SW261-1, also with a small seconds complication at 6:00.  The main difference is in the position of the small seconds hand pinion. On the SW260-1 being discussed here, the seconds hand is positioned higher on the dial, closer to the central hours and minutes. The SW261-1 small seconds hand is about .8mm farther away from the center than the SW260-1. See the image below from Sellita:

Manual-Wind Version:

Sellita offers a manual-wind version of this caliber, designated as SW216-1.

4 Grades of SW260-1:

Just like the SW200-1, there are four grades of the SW260-1 movement:

• Standard – adjusted in two positions; accuracy of +/-12 sec/day up to +/- 30 sec/day
• Special (Elabore) – adjusted in three positions; accuracy of +/-7 sec/day up to +/- 20 sec/day
• Premium (Top) – adjusted in five positions; accuracy of +/-4 sec/day up to +/- 15 sec/day
• Chronometer – COSC criteria

SW260-1 Crown/Stem Removal:

If you want to remove the movement from your watch, you will likely need to extract the stem first. Official Sellita documentation states that the crown should be in the time setting position before being extracted. Use a 1mm screw-driver to carefully press the detent button in the hole near the steam. Avoid using tweezers or any other tool with a point because this could jam the setting lever and damage the setting lever spring.
