Product Details

Sinn Retirement Update

Last year, Sinn announced the retirement of all Sinn 657 watches. Since these were among our best selling models, we loaded up our last order and they sold out quickly. We thought this was the end of the series - we were wrong.

Sinn has been able to produce a few additional pieces of the Sinn 657; the result - this is our last shipment and the series is no longer in production by Sinn.

The Sinn 657 is the perfect size for many watch fans because of the case size - it's 40 mm and includes a bezel.

Features include:

Bezel is screwed to the case using a exclusive Sinn design
Extreme magnetic field protection to 80,000 A/m
Nickel free case back
Double coated anti-reflective sapphire crystal
Vacuum safe for high flight altitudes
In house case construction from Sinn's affiliated company in Glashutte, Germany
200 meter water resistance

The special case design and inner lining consist of a special iron core making this watch resistant to the effects of magnetism. It is the perfect watch for pilots, frequent flyers or anyone whose work takes them to high altitudes or other areas of magnetism.

Without being shiny, the dial in the Sinn 657 has a slightly shiny finish and features Arabic numerals with offset date display at 4:30. The design and layout of this watch make it extremely easy to read in virtually all light conditions. The case has a satin finish.

Sapphire crystal with luminous hands and hour markers. Case size is 40 mm.

Comments about this watch: I ordered my Sinn 657 in July, I have been wearing it every day since, it wears very nice; it has good feel to it. It is my first automatic watch and I hope to wear it looking this good for many years to come.

Comments about this watch: I've owned this watch for about 6 months now. I changed the band to black Kevlar with a deployment buckle (non-Sinn). In low light and when occupied with other tasks (like flying) it is highly visible and easy to read. The simple design is very classy and functional. As a pilot and law enforcement official, it fits right in. My 657 runs about + 4 sec a day. Looks better in person.
