Frequently Asked Questions
What lug width is the Mini Turtle?
The Seiko SRPC35 Mini Turtle has a 20mm lug width.
Is the Mini Turtle actually smaller than the Turtle?
Despite the 'Mini' name, the case diameter is 42.3mm vs the Turtle's 45mm. The lug-to-lug is notably shorter at 44mm vs 48mm, which makes it wear significantly smaller on the wrist.
Can I use regular Turtle parts on the Mini Turtle?
No. The Mini Turtle has a different case size, so bezels, bezel inserts, and crystals are not interchangeable with the regular Turtle. The lug width is also 20mm vs 22mm.
