The Sellita SW215-1 is the main competitor to the ETA caliber 2804-2, but with an additional 2 jewels. You may have seen this movement written as the SW-215 but according to Sellita, the correct way to spell this caliber number is SW215 without a hyphen. Many reputable watch companies are using this movement as an alternative to the ETA mechanism due to it being more economical and readily available.

Current documentation for this caliber is dated 9/20/2018, so this movement is at least this old.

In Sellita’s own words:

“Manual winding version of the SW200-1, the SW215-1 is striking notably for its slimness (only 3.35 mm with date and central sweep seconds), reliability and robustness. Just like the SW200-1, the SW215-1 comes in many versions, including numerous small complications.”

Finishes:

The caliber SW215-1 is available from Sellita in 3 different finishes: Standard, Refined, and Tailor-Made.

Standard Finish – Bulk sand-blasted and nickel plated. Options include engravings, blue screws, rhodium plated, gold plated.

Love this movement. I have it in my Cincinnati Watch Co P-40M Mechanical. I keep it wound daily and it keep impeccable time. I’m surprised, as I had a bad experience with an SW200. But, this manual version is sublime. Smooth, quiet, and the sweep is lovely for the price of the watch it’s in.
