The Janome 423S has adjustable stitch length, width and presser-foot pressure, plus a one-step buttonhole. Its purchase status depends on region: Janome America lists its manual under retired models, while Janome UK & Ireland still documents the 423S in its mechanical range. US retired status does not mean every 423S worldwide is a used machine.
What the regional documentation establishes
| Question | Documented answer | Buying consequence |
|---|---|---|
| UK stitch selection | 24 built-in stitch choices | Inspect the exact selector and regional package |
| Stitch dimensions | Adjustable width and length | More control than preset dimensions |
| Buttonhole | Automatic one-step | Try a repeated buttonhole using the actual button and interfacing |
| Pressure | User-adjustable | Can be changed for fabric behavior; not proof of perfect feeding |
| Bobbin access | Front-loading removable case | Try case insertion and identify a missing replacement |
| Sewing speed | Pedal controlled | No separate speed slider or needle-position button |

Try the pressure and buttonhole controls
The pressure control is a useful distinction for buyers changing fabrics. Use the manual’s starting setting, sew representative scrap, and adjust one variable at a time while checking feeding and the seam from both sides. Foot pressure is not thread tension, and extra foot lift is a separate loading-access feature.
For garment work, use the supplied one-step buttonhole arrangement with actual fabric and interfacing. Test that the hole fits before cutting it. For a hem, include the existing seam crossing. Neither metal construction nor a maximum speed establishes the thickness it will reliably sew on your project.
Buying a used or imported unit
Inspect the badge and readable electrical plate, correct controller/lead, bobbin case, foot holder and included feet. Demonstrate straight stitch, zigzag, reverse, winding, pressure adjustment and the buttonhole. A power-on photograph cannot establish all those functions.
Match the electrical rating to the place of use and confirm a regional service path. A plug adapter or similar controller connector does not establish compatibility. The manual shows cleaning and oiling at specific points; follow that procedure after unplugging rather than applying another model’s maintenance rule.
Compare machine price + missing compatible parts + quoted service + delivery. For a new regional offer, check the exact warranty and seller eligibility. A UK model page does not create a new US warranty.
How the linked alternative differs
The linked SINGER M1500 is a different US model. It is not an equivalent 423S: SINGER documents preset stitch dimensions and a four-step buttonhole . Buyers choosing the 423S specifically for pressure adjustment or a one-step buttonhole should not accept a generic basic-machine substitution.
Verdict
Shortlist the 423S for its actual adjustable controls and one-step buttonhole, with the exact regional unit and support verified. Compare another model if top-loading access, speed limiting or a current US package is required. This is a researched review without a hands-on reliability, learning-time or comparative strength result.
